Amirul Jihad and the Military of the Khilafah: The Ummah’s Shield Submissive to Shariah
Dear readers, if we observe the geopolitical map of the world today — from Palestine bleeding endlessly under blockade, the Rohingya expelled from their homeland by their own military, Uyghurs gathered in rehabilitation camps, to Yemen being bombed by an Arab coalition — one great question will arise in our minds: “Why is the Muslim Ummah so militarily weak?”
The paradox is devastating. Today, dozens of Muslim countries have a combined military budget of hundreds of billions of dollars. Saudi Arabia, Pakistan, Turkey, Egypt — all have armed forces, tanks, fighter jets, even ballistic missiles. Yet when the Muslim Ummah needs defense, all that power is paralyzed. Not one dares to move.
Why? Because the military in secular states is not designed to defend the Ummah. It is designed to protect the ruling regime. It is an instrument of oppression directed at its own people, not a shield protecting them from enemies.
In the Khilafah system, the military has an entirely different philosophy. It is not a political tool. It is not a coup machine. It is the shield of the Ummah — a force built to intimidate the enemies of Allah ﷻ and protect every soul under the protection of Islam, Muslim and non-Muslim alike.
Through the lens of Hizbut Tahrir’s tsaqofah, particularly the book Nizhamul Hukm fil Islam by Sheikh Taqiuddin An-Nabhani and Mafahim Hizbut Tahrir, we will comprehensively explore the defense and military system of the Khilafah. From the structure of Amirul Jihad, the division of regular and reserve forces, military industry independence, to the rules of war unknown to any Geneva Convention.
Let us explore 10 important points about the military of the Khilafah.
1. Introduction: Why Defense Is Not a Choice, But an Obligation
Every country in the world has armed forces. The United States has the Pentagon with a budget of over 800 billion dollars per year. China has the People’s Liberation Army with 2 million active personnel. Russia has the world’s largest nuclear arsenal. No country feels secure enough without a military.
The question is not “does the Khilafah need a military?” — because that is certain. The question is: “what kind of military does the Khilafah build, and what is it used for?”
In secular states today, the military often becomes an instrument of oppression. In Egypt, the military killed thousands of its own people at Rab’ah Al-Adawiyah. In Syria, the Assad regime used tanks and fighter jets to destroy cities that opposed it. In Myanmar, the military brutally burned Rohingya villages. In Turkey, the military staged repeated coups and massacred Kurdish activists.
This is the face of the secular military: strong outwardly, but directed inward — to oppress its own people.
Islam came with a different philosophy. The military in the Khilafah is not a political tool. It must not be used to overthrow the Khalifah. It must not participate in power competitions. The military is a defense department — an institution with only one function: protecting Darul Islam from external aggression and establishing justice throughout the world.
Allah ﷻ says:
وَأَعِدُّوا لَهُمْ مَا اسْتَطَعْتُمْ مِنْ قُوَّةٍ وَمِنْ رِبَاطِ الْخَيْلِ تُرْهِبُونَ بِهِ عَدُوَّ اللَّهِ وَعَدُوَّكُمْ
“And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy.” (QS. Al-Anfal [8]: 60)
“Whatever you are able of power” — this is not a suggestion. It is a command. Allah ﷻ commands the Muslims to prepare military strength. The word quwwah (strength) here is general — encompassing all forms of military strength available in every era: in the time of the Prophet ﷺ it was swords, arrows, and horses; in our time it is fighter jets, warships, missiles, and cyber defense.
2. Definition of Amirul Jihad: Head of the Defense Department
In the governance structure of the Khilafah, Amirul Jihad (أمير الجهاد) is one of the 13 pillars (mu’assasat) of the state. He is not a defense minister as in democratic states. His position is far more strategic and he is directly accountable to the Khalifah.
أَمِيرُ الْجِهَادِ: هُوَ رَئِيسُ جِهَازِ الدِّفَاعِ فِي الدَّوْلَةِ الْإِسْلَامِيَّةِ
“Amirul Jihad is the head of the defense department in the Islamic state.”
Table 1: Military Terminology in the Khilafah
| Term | Meaning | Function |
|---|---|---|
| Amirul Jihad (أمير الجهاد) | Commander of War | Head of the defense department |
| Khalifah (الخليفة) | General Leader | Supreme commander |
| Jund (جند) | Soldier | Professional regular forces |
| Jundiyah (جندية) | Soldiering | Active military status |
| Ihtiyath (احتياط) | Reserve | Reservist forces |
| Ribat (رباط) | Border guarding | Military posts on the front lines |
Amirul Jihad is an operational position. He leads troops, designs strategy, and manages the defense department on a daily basis. However, the final decision to declare war or a ceasefire rests with the Khalifah. Amirul Jihad may not announce war without the Khalifah’s order. This is a fundamental principle that prevents the military from becoming an independent political actor.
The Messenger of Allah ﷺ said about the importance of obedience to the leader in military affairs:
مَنْ أَطَاعَنِي فَقَدْ أَطَاعَ اللَّهَ، وَمَنْ عَصَانِي فَقَدْ عَصَى اللَّهَ، وَمَنْ أَطَاعَ أَمِيرِي فَقَدْ أَطَاعَنِي، وَمَنْ عَصَى أَمِيرِي فَقَدْ عَصَانِي
“Whoever obeys me has obeyed Allah, and whoever disobeys me has disobeyed Allah. And whoever obeys my commander has obeyed me, and whoever disobeys my commander has disobeyed me.” (HR. Bukhari no. 2859)
“Obey my commander” — The Messenger of Allah ﷺ himself appointed war commanders (such as Khalid bin Walid) and ordered the troops to obey them. However, the commander himself remained under the command of the Messenger of Allah ﷺ. This chain of command must be maintained: Soldier → Amirul Jihad → Khalifah → Shariah.
Comparison: Amirul Jihad vs. Secular Defense Minister
| Aspect | Amirul Jihad (Khilafah) | Secular Defense Minister |
|---|---|---|
| Source of legitimacy | Appointed by the Khalifah based on kafa’ah (competence) | Appointed by the president/PM based on politics |
| Accountability | Accountable to the Khalifah and Shariah | Accountable to parliament/legislature |
| Military objective | Protecting Darul Islam + establishing global justice | Protecting national interests (may be secular) |
| War authority | Not allowed without the Khalifah’s order | Can be proposed, but usually requires parliamentary approval |
| Political involvement | Totally prohibited | Often involved in politics (even running for president) |
3. Shariah Basis: Evidences for the Obligation of Military Defense
The military defense system of the Khilafah is not a rationalist construction adapted from the West. It is built upon very strong evidences from the Qur’an and the Sunnah.
First Evidence: The Command to Prepare Strength (QS. Al-Anfal: 60)
وَأَعِدُّوا لَهُمْ مَا اسْتَطَعْتُمْ مِنْ قُوَّةٍ وَمِنْ رِبَاطِ الْخَيْلِ تُرْهِبُونَ بِهِ عَدُوَّ اللَّهِ وَعَدُوَّكُمْ
“And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy.” (QS. Al-Anfal [8]: 60)
This verse is the most fundamental basis. The word a’iddū (Prepare!) is an imperative verb — a command. And a command in Islam signifies obligation. Therefore, preparing military strength is obligatory.
Second Evidence: The Obligation of Jihad
كُتِبَ عَلَيْكُمُ الْقِتَالُ وَهُوَ كُرْهٌ لَكُمْ ۖ وَعَسَىٰ أَنْ تَكْرَهُوا شَيْئًا وَهُوَ خَيْرٌ لَكُمْ ۖ وَعَسَىٰ أَنْ تُحِبُّوا شَيْئًا وَهُوَ شَرٌّ لَكُمْ ۗ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لَا تَعْلَمُونَ
“Fighting has been enjoined upon you while it is hateful to you. But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah knows, while you know not.” (QS. Al-Baqarah [2]: 216)
“Fighting has been enjoined upon you” — Allah ﷻ uses the word kutiba (enjoined/obligated), not mustahabb (recommended). This indicates that jihad fi sabilillah — including military combat — is a Shariah obligation that cannot be neglected.
Third Evidence: Self-Defense When Attacked
وَقَاتِلُوا فِي سَبِيلِ اللَّهِ الَّذِينَ يُقَاتِلُونَكُمْ وَلَا تَعْتَدُوا ۚ إِنَّ اللَّهَ لَا يُحِبُّ الْمُعْتَدِينَ
“Fight in the way of Allah those who fight you but do not transgress. Indeed, Allah does not like transgressors.” (QS. Al-Baqarah [2]: 190)
This verse establishes two principles: (1) Defensive jihad is obligatory when Darul Islam is attacked, and (2) the prohibition of transgression in warfare — including not killing civilians, not destroying places of worship, and not torturing prisoners.
Fourth Evidence: The Warning for Those Who Refuse Jihad
يَا أَيُّهَا الَّذِينَ آمَنُوا مَا لَكُمْ إِذَا قِيلَ لَكُمُ انْفِرُوا فِي سَبِيلِ اللَّهِ اثَّاقَلْتُمْ إِلَى الْأَرْضِ ۚ أَرَضِيتُمْ بِالْحَيَاةِ الدُّنْيَا مِنَ الْآخِرَةِ ۚ فَمَا مَتَاعُ الْحَيَاةِ الدُّنْيَا فِي الْآخِرَةِ إِلَّا قَلِيلٌ
“O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] little.” (QS. At-Tawbah [9]: 38)
“The enjoyment of worldly life … is very little” — Allah ﷻ rebukes those who prefer worldly comfort over jihad. This is a stern warning that abandoning the obligation of defense is a major sin.
Table 2: Summary of Military Defense Evidences
| Evidence | Source | Established Ruling |
|---|---|---|
| ”Prepare whatever strength you are able” | QS. Al-Anfal [8]: 60 | Obligation to prepare military |
| ”Fighting is enjoined upon you” | QS. Al-Baqarah [2]: 216 | Jihad is an obligation |
| ”Fight those who fight you, do not transgress” | QS. Al-Baqarah [2]: 190 | Defensive jihad obligatory, prohibition of excess |
| ”Why do you feel heavy to go forth for jihad?” | QS. At-Tawbah [9]: 38 | Abandoning jihad = major sin |
| ”Obey my commander” | HR. Bukhari no. 2859 | Obligation to obey in military command |
| ”Hear and obey even if an Abyssinian slave leads you” | HR. Muslim no. 1840 | Obedience to the leader does not depend on social status |
The Messenger of Allah ﷺ said:
مَنْ مَاتَ وَلَمْ يَغْزُ وَلَمْ يُحَدِّثْ بِهِ نَفْسَهُ مَاتَ عَلَى شُعْبَةٍ مِنْ نِفَاقٍ
“Whoever dies without having fought or even intended to fight, dies upon a branch of hypocrisy.” (HR. Muslim no. 1910)
“A branch of hypocrisy” — this is not kufr, but it is a very severe warning. A person who has no desire to defend his religion and his Ummah — even in his heart — possesses a trait resembling hypocrisy.
4. Structure of the Khilafah’s Military: A Clear Chain of Command
The military structure of the Khilafah is very simple yet effective. There is no complicated bureaucracy, no parallel institutions overlapping each other. The entire chain of command converges on one point: the Khalifah.
Table 3: Military Command Hierarchy of the Khilafah
| Level | Position | Function |
|---|---|---|
| 1 | Khalifah | Supreme commander. The only one entitled to declare war, ceasefire, and total mobilization. |
| 2 | Amirul Jihad | Head of the defense department. Executes the Khalifah’s orders, leads troops on the battlefield, manages logistics. |
| 3 | Field Commanders | Lead divisions, brigades, and battalions on the battlefield. Appointed by Amirul Jihad. |
| 4 | Regular Forces (Jundiyah) | Professional soldiers serving full-time. Paid from the Baitul Mal. |
| 5 | Reserve Forces (Ihtiyath) | All able-bodied adult males with basic military capability. Called upon in emergencies. |
Note how clear this chain of command is: the Khalifah is the head of state and supreme commander. He does not delegate war authority to anyone — because war is the most crucial political-strategic decision. Amirul Jihad exercises that authority as an executor, not as an independent decision-maker.
Comparison with Modern Systems
In democratic states, the military chain of command is often blurred. The president is the constitutional supreme commander, but parliament has the right to declare war, allocate budgets, and investigate military operations. The result? The military becomes an arena of political tug-of-war. In Turkey, the military staged 4 coups between 1960-1997. In Egypt, the military has been the dominant political force since 1952. In Pakistan, the military and civilian government are in continuous conflict.
In the Khilafah, this problem does not exist. The military is not a political entity. It is a technical department executing the Khalifah’s orders. If the Khalifah orders war, Amirul Jihad carries it out. If the Khalifah orders a ceasefire, Amirul Jihad stops. There is no debate, no coup, no army stopping its own leader.
5. Regular Forces vs. Reserves: Two Layers of Complementary Defense
The Khilafah builds a very intelligent two-layer defense system: professional regular forces and massive reserve forces. They complement each other — one guards every day, the other is ready to mobilize in emergencies.
Regular Forces (Jundiyah)
Regular forces are professional soldiers. They dedicate their entire time and energy to the defense of the state. These are the “army” in the sense we commonly understand.
Characteristics of Regular Forces:
| Aspect | Detail |
|---|---|
| Status | Full-time |
| Income | Paid from the Baitul Mal |
| Training | Intensive and continuous |
| Readiness | 24 hours, 365 days |
| Main duties | Guarding borders, securing territory, routine training, military operations |
| Recruitment | Voluntary, based on qualifications |
Evidence Regarding Regular Forces:
The Messenger of Allah ﷺ said:
ارْبِطُوا الْخَيْلَ وَلَا تُحِلُّوهَا فَإِنَّهَا قَرَائِنُ فِي أَعْنَاقِهَا أَجَلُهَا
“Tether the horses and do not release them, for goodness is tied to their forelocks until the Day of Resurrection.” (HR. Bukhari no. 2851)
“Tether the horses” — The Messenger of Allah ﷺ commanded that warhorses always be ready, not simply released. This indicates the existence of forces always in a state of readiness — what we today call regular forces.
In history, the Messenger of Allah ﷺ himself directly led 27 military expeditions (ghazwah) and sent dozens of military expeditions (sariyyah). He ﷺ did not merely wait for the enemy to come — he ﷺ prepared troops, sent intelligence, and mobilized regular forces for strategic missions.
Reserve Forces (Ihtiyath)
Reserve forces are the second layer of defense. They are not professional soldiers. They are ordinary citizens — farmers, merchants, teachers, engineers — who have basic military capability and are ready to be called upon when the state needs them.
Characteristics of Reserve Forces:
| Aspect | Detail |
|---|---|
| Status | Part-time (ordinary civilians) |
| Income | Not paid when inactive; when mobilized, paid from the Baitul Mal |
| Training | Periodic (e.g., seasonal training) |
| Readiness | Called upon in emergencies (defensive jihad) |
| Main duties | Defending Darul Islam when attacked, reinforcing regular forces |
| Membership | All able-bodied adult males |
Evidence Regarding Reserve Forces:
The Messenger of Allah ﷺ called upon all able-bodied adult males in several important battles:
- Battle of Uhud (3 AH): The Messenger of Allah ﷺ called upon all men of Madinah capable of bearing arms. About 1,000 set out. When 300 hypocrites withdrew mid-journey, the remaining 700 continued to fight.
- Battle of the Trench (5 AH): All men of Madinah — including the Messenger of Allah ﷺ himself — went to the field to dig a trench around the city. No one was exempted.
- Battle of Tabuk (9 AH): A general call for jihad. The entire capacity of the Ummah was mobilized. Even Uthman bin Affan contributed 1,000 camels for the expedition’s costs.
Allah ﷻ says:
وَمَا كَانَ الْمُؤْمِنُونَ لِيَنْفِرُوا كَافَّةً ۚ فَلَوْلَا نَفَرَ مِنْ كُلِّ فِرْقَةٍ مِنْهُمْ طَائِفَةٌ لِيَتَفَقَّهُوا فِي الدِّينِ وَلِيُنْذِرُوا قَوْمَهُمْ إِذَا رَجَعُوا إِلَيْهِمْ لَعَلَّهُمْ يَحْذَرُونَ
“And it is not for the believers to go forth [to battle] all at once. For there should separate from every division of them a group [remaining] to obtain understanding in the religion and warn their people when they return to them that they might be cautious.” (QS. At-Tawbah [9]: 122)
This verse shows a brilliant principle: not everyone must be a professional soldier. Some go to battle, others seek knowledge, trade, and care for society. But when emergency strikes, all are ready.
Table 4: Comparison of Regular vs. Reserve Forces
| Aspect | Regular Forces | Reserve Forces |
|---|---|---|
| Professionalism | High (full-time, trained) | Basic (periodic training) |
| Readiness | Always ready (24/7) | Called upon in emergencies |
| Numbers | Limited (as needed) | Massive (all able-bodied adult males) |
| Financing | Baitul Mal (regular) | Baitul Mal (when mobilized) |
| Historical example | Khalid bin Walid’s forces in Syria | All residents of Madinah at the Trench |
6. Military Industry Independence: No Dependence on Enemies
This is a principle often forgotten even by many Muslim countries today: the Khilafah must be independent in military industry. It must not depend on other countries for weapons, ammunition, combat vehicles, or defense technology.
Why? Because military dependence is a form of weakness that enemies can exploit.
Imagine this scenario: the Khilafah buys fighter jets from Country X. Then diplomatic tensions arise. Country X halts spare parts shipments. Those jets become hangar decorations. The Khilafah loses air capability — not because it was defeated on the battlefield, but because of logistical dependence.
This is what happened in Egypt when the US halted military aid after the 2013 coup. In Pakistan when Western sanctions hindered the nuclear program. In Iraq when arms embargoes weakened Saddam Hussein’s military.
Islam does not allow such vulnerability. Allah ﷻ says:
وَأَعِدُّوا لَهُمْ مَا اسْتَطَعْتُمْ مِنْ قُوَّةٍ
“And prepare against them whatever you are able of power.” (QS. Al-Anfal [8]: 60)
“Whatever you are able” — this phrase carries deep meaning. “Able” means having the capacity to produce, not just to buy. If the Khilafah can only buy weapons from abroad, it is not truly “able” — it is only “able to pay.” And the ability to pay can disappear at any time if diplomatic relations deteriorate.
Principles of Military Industry Independence
| Principle | Explanation |
|---|---|
| Domestic production | Weapons, ammunition, combat vehicles must be produced in Darul Islam |
| Technology transfer | If technology import is necessary, it must be accompanied by knowledge transfer |
| Ammunition self-sufficiency | Bullets, bombs, missiles must be producible independently |
| Supporting industries | Steel, fuel, electronics — all military-supporting industries must exist |
| Continuous innovation | Military research and development must proceed continuously |
Table 5: Military Industry Independence — What Must Be Produced
| Category | Items | Urgency |
|---|---|---|
| Light weapons | Rifles, pistols, grenades | Absolute (basic defense) |
| Ammunition | Bullets, missiles, bombs | Absolute (without ammunition, weapons are useless) |
| Combat vehicles | Tanks, APCs, military trucks | High |
| Aircraft | Fighters, transport, reconnaissance | High |
| Warships | Frigates, submarines, patrol boats | High (for coastal lines) |
| Cyber defense | Network security, digital intelligence | Critical (modern era) |
| Military communications | Encrypted radios, satellites | High |
The Khilafah has a Department of Industry (Jihaz at-Shina’ah) tasked with managing this independence. This department does not only produce weapons, but also ensures that the entire military industry supply chain — from raw materials to finished products — is under the control of Darul Islam.
Visual Analogy: Understanding Military Independence
To understand how crucial this independence is, let us use two analogies.
Analogy 1: The Iron Shield Escorting the Caravan
Imagine the Muslim Ummah as a great caravan crossing a dangerous desert. Along the route, there are bandits, wild beasts, and storms. The military of the Khilafah is the iron shield surrounding the caravan — not to attack indiscriminately, but to ensure every member reaches their destination safely. This shield does not determine the caravan’s direction — that is the Navigator’s (Khalifah’s) role. If the shield is used to attack the caravan it was meant to protect, it has betrayed its function. This is what happens when a secular military stages a coup.
Analogy 2: The Body’s Immune System
Imagine Darul Islam as a human body. The military of the Khilafah is the immune system — white blood cells fighting viruses from outside. This system does not decide on its own when to attack — it moves according to the brain’s (Khalifah’s) command. When a virus enters, the brain sends the signal: “Fight!” But white blood cells never attack the body’s own organs — if that happens, it is called an autoimmune disease. A military coup is exactly that: political autoimmunity, when the state’s defense turns against the state itself.
7. Moral Control Over the Military: No Politics, No Coups
This is the most fundamental difference between the military of the Khilafah and the military of secular states: the Khilafah’s military is entirely uninvolved in politics. It is not a party. It is not a pressure group. It is not a kingmaker.
Fundamental Principle: The Military Under Shariah
The military in the Khilafah operates within three boundaries that cannot be violated:
First: The military acts only upon the Khalifah’s order. Amirul Jihad may not declare war on his own. Field commanders may not halt troops without orders. All military operations must be within the chain of command converging on the Khalifah.
Second: The military must not participate in politics. Soldiers must not be party members. Amirul Jihad must not run for Khalifah while still active. The military must not be a pressure group pushing the Khalifah for certain policies.
Third: The military must not stage coups. This is the most emphatic principle. In the Khilafah, a military coup is the greatest crime. Not only because it overthrows a legitimate leader, but because it destroys the entire Shariah system that leadership protects.
Table 6: What the Khilafah’s Military MAY and MAY NOT Do
| ✅ ALLOWED | ❌ NOT ALLOWED |
|---|---|
| Guarding the borders of Darul Islam | Staging a coup against the Khalifah |
| Executing the Khalifah’s orders in war | Participating in political party activities |
| Training reserve forces | Openly opposing the Khalifah’s decisions |
| Developing military industry | Forming internal factions within the military |
| Protecting Muslim and non-Muslim citizens | Oppressing civilian populations |
Evidence Prohibiting Coups and Rebellion
The Messenger of Allah ﷺ said:
مَنْ رَأَى مِنْ أَمِيرِهِ شَيْئًا يَكْرَهُهُ فَلْيَصْبِرْ عَلَيْهِ فَإِنَّهُ مَنْ فَارَقَ الْجَمَاعَةَ شِبْرًا فَمَاتَ إِلَّا مَاتَ مِيتَةً جَاهِلِيَّةً
“Whoever sees from his leader something he dislikes, let him be patient. For whoever separates from the jama’ah by even a handspan and then dies, dies a death of Jahiliyyah.” (HR. Bukhari no. 7054 and Muslim no. 1849)
“Dies a death of Jahiliyyah” — The Messenger of Allah ﷺ warned severely against anyone who separates from legitimate leadership, even if he sees something he dislikes from his leader. This is a very stern warning against military coups.
The Messenger of Allah ﷺ also said:
اسْمَعُوا وَأَطِيعُوا وَإِنِ اسْتُعْمِلَ عَلَيْكُمْ عَبْدٌ حَبَشِيٌّ كَأَنَّ رَأْسَهُ زَبِيبَةٌ
“Hear and obey, even if an Abyssinian slave whose head is like a raisin is appointed over you.” (HR. Bukhari no. 672)
“Even if the leader is an Abyssinian slave” — The Messenger of Allah ﷺ made no exceptions based on race, social status, or physical appearance. As long as the leader is legitimate (pledged allegiance through Shariah), obedience to him is obligatory.
What If the Khalifah Is Unjust?
This does not mean the Khalifah can do as he pleases. In the Khilafah, there are independent accountability mechanisms:
- Mahkamah Mazhalim — a special court that can try the Khalifah if he violates Shariah.
- People’s Assembly — a representative body that can criticize and oversee the Khalifah’s policies.
- The Ummah’s right to remove the Khalifah — if the Khalifah is proven to seriously and persistently violate Shariah, the Ummah has the right to remove him through a lawful legal process, not through a coup.
The difference is very clear: a coup is violence that destroys the system. Removing the Khalifah through the Mahkamah Mazhalim is a legal process that preserves the system. The first is chaos. The second is governance.
8. Rules of War in Islam: Standards Preceding the Geneva Conventions by 1,300 Years
Before the world knew the Geneva Conventions (1949), before the UN drafted the Universal Declaration of Human Rights (1948), Islam had already established very strict and humane rules of war. The Messenger of Allah ﷺ himself taught them — 1,400 years before the modern world bothered to think about them.
Rules of War from the Messenger of Allah ﷺ
The Messenger of Allah ﷺ said when dispatching troops:
اغْزُوا بِاسْمِ اللَّهِ، وَفِي سَبِيلِ اللَّهِ، قَاتِلُوا مَنْ كَفَرَ بِاللَّهِ، اغْزُوا وَلَا تَغُلُّوا وَلَا تَغْدِرُوا وَلَا تُمَثِّلُوا وَلَا تَقْتُلُوا وَلِيدًا
“Fight in the name of Allah and in the path of Allah. Fight those who disbelieve in Allah. Fight and do not betray, do not take property unlawfully (ghulul), do not mutilate, and do not kill a child.” (HR. Muslim no. 1731)
The Messenger of Allah ﷺ also said:
لَا تَقْتُلُوا عَجُوزًا وَلَا وَلِيدًا وَلَا صَغِيرًا وَلَا امْرَأَةً وَلَا تَقْطَعُوا شَجَرًا مُثْمِرًا وَلَا تَخْرِمُوا بَيْتًا
“Do not kill an old person, a child, a young one, or a woman. Do not cut down a fruit-bearing tree and do not destroy a house.” (HR. Abu Dawud no. 2614)
Table 7: Rules of War in Islam
| Prohibition | Description | Evidence |
|---|---|---|
| Killing women | Haram to kill women not participating in war | HR. Muslim no. 1731 |
| Killing children | Haram to kill underage children | HR. Muslim no. 1731 |
| Killing the elderly | Haram to kill those unable to fight | HR. Abu Dawud no. 2614 |
| Killing monks/clergy | Haram to kill those worshipping in places of worship | HR. Abu Dawud no. 2614 |
| Cutting trees | Haram to destroy crops and the environment | HR. Abu Dawud no. 2614 |
| Destroying places of worship | Haram to damage churches, synagogues, or temples | HR. Abu Dawud no. 2614 |
| Torturing prisoners | Haram to harm prisoners who have surrendered | HR. Ahmad |
| Mutilating corpses | Haram to disfigure enemy dead | HR. Muslim no. 1731 |
| Betraying treaties | Haram to violate peace agreements | QS. Al-Anfal [8]: 27 |
| Killing non-combatant civilians | Haram to attack those not involved in war | QS. Al-Baqarah [2]: 190 |
Treatment of Prisoners of War
Islam has very clear rules regarding prisoners of war. They must not be tortured, arbitrarily killed, or treated inhumanely.
Allah ﷻ says:
وَيُطْعِمُونَ الطَّعَامَ عَلَىٰ حُبِّهِ مِسْكِينًا وَيَتِيمًا وَأَسِيرًا
“And they give food in spite of love for it to the needy, the orphan, and the captive.” (QS. Al-Insan [76]: 8)
“And the captive” — Allah ﷻ mentions prisoners of war alongside the poor and orphans as parties entitled to food and good treatment. This is a very high standard. Even an enemy captured on the battlefield is entitled to adequate food and humane treatment.
Options Regarding Prisoners
The Khalifah has several options in handling prisoners of war:
| Option | Description | Evidence |
|---|---|---|
| Released freely | Without conditions, as an act of kindness | QS. Muhammad [47]: 4 |
| Released for ransom | Prisoners are ransomed or exchanged for Muslim prisoners | QS. Muhammad [47]: 4 |
| Detained | If there are strategic reasons | QS. Muhammad [47]: 4 |
| Enslaved | (Historical context — no longer relevant in the modern era) | — |
Allah ﷻ says:
فَإِذَا لَقِيتُمُ الَّذِينَ كَفَرُوا فَضَرْبَ الرِّقَابِ حَتَّىٰ إِذَا أَثْخَنْتُمُوهُمْ فَشُدُّوا الْوَثَاقَ فَإِمَّا مَنًّا بَعْدُ وَإِمَّا فِدَاءً حَتَّىٰ تَضَعَ الْحَرْبُ أَوْزَارَهَا
“So when you meet those who disbelieve [in battle], strike [their] necks until, when you have inflicted slaughter upon them, then secure their bonds, and either [confer] favor afterwards or ransom [them] until the war lays down its burdens.” (QS. Muhammad [47]: 4)
Note the order in this verse: (1) Fight, (2) Take captive those who are defeated, (3) Release or accept ransom. There is no option to kill prisoners who have surrendered. This is a standard that even many modern states do not possess.
9. Stories of War in the Sirah: Three Battles That Changed History
There is no better way to understand the military of the Khilafah than to see directly how the Messenger of Allah ﷺ led his troops. The following three battles provide very valuable lessons about strategy, faith, and the rules of war.
Battle of Badr (2 AH / 624 CE) — When 313 Defeated 1,000
The Battle of Badr was the first and most decisive battle in Islamic history.
Conditions:
| Side | Numbers | Armament |
|---|---|---|
| Muslims | 313 men | 2 horses, 70 camels (shared), minimal swords and arrows |
| Quraysh | ~1,000 men | 100 horses, 700 camels, full swords and armor |
Strength ratio: 1 to 3. By military logic, the Muslims should have been decisively defeated.
Strategy of the Messenger of Allah ﷺ:
The Messenger of Allah ﷺ chose a strategic position near the wells of Badr. He ﷺ positioned his troops on higher ground giving them a positional advantage. He ﷺ also prayed earnestly to Allah ﷻ on the night before the battle.
Allah ﷻ says:
وَلَقَدْ نَصَرَكُمُ اللَّهُ بِبَدْرٍ وَأَنْتُمْ أَذِلَّةٌ ۖ فَاتَّقُوا اللَّهَ لَعَلَّكُمْ تَشْكُرُونَ إِذْ تَقُولُ لِلْمُؤْمِنِينَ أَلَنْ يَكْفِيَكُمْ أَنْ يُمِدَّكُمْ رَبُّكُمْ بِثَلَاثَةِ آلَافٍ مِنَ الْمَلَائِكَةِ مُنْزَلِينَ
“And Allah had already given you victory at Badr while you were few in number. Then fear Allah; perhaps you will be grateful. [Remember] when you said to the believers, ‘Is it not sufficient for you that your Lord should reinforce you with three thousand angels sent down?’” (QS. Ali ‘Imran [3]: 123-124)
Result: Quraysh was defeated. 70 killed, 70 taken captive. The Muslims lost 14 martyrs.
Lesson: The quality of troops — faith, discipline, and strategy — is more decisive than quantity. And the help of Allah ﷻ comes when the Ummah is sincere.
Battle of the Trench (5 AH / 627 CE) — A Defensive Innovation That Saved Madinah
The Battle of the Trench was the greatest test Madinah ever faced.
Conditions:
| Side | Numbers | Situation |
|---|---|---|
| Muslims | ~3,000 men | Defending within Madinah |
| Confederates (Ahzab) | ~10,000 men | Surrounding Madinah from all sides |
Strength ratio: 1 to 3.3. Madinah was besieged. Food supplies were limited. The weather was cold. The troops’ morale was tested.
Strategy: Salman Al-Farisi’s Idea
Salman Al-Farisi (may Allah be pleased with him) proposed an idea never before seen in the Arabian Peninsula: digging a trench around Madinah. This idea came from Persia — Salman’s homeland — where trenches were used as a defense against enemy cavalry.
The Messenger of Allah ﷺ accepted the idea and participated in digging the trench alongside the companions. He ﷺ did not merely command from behind — he ﷺ went to the field, lifted soil, and felt the same exhaustion as his troops.
Allah ﷻ says:
يَا أَيُّهَا الَّذِينَ آمَنُوا اذْكُرُوا نِعْمَةَ اللَّهِ عَلَيْكُمْ إِذْ جَاءَتْكُمْ جُنُودٌ فَأَرْسَلْنَا عَلَيْهِمْ رِيحًا وَجُنُودًا لَمْ تَرَوْهَا ۚ وَكَانَ اللَّهُ بِمَا تَعْمَلُونَ بَصِيرًا
“O you who have believed, remember the favor of Allah upon you when armies came to [attack] you and We sent upon them a wind and armies [of angels] you did not see. And Allah is ever, of what you do, Seeing.” (QS. Al-Ahzab [33]: 9)
Result: The trench successfully stopped the enemy cavalry. After a siege of nearly a month, Allah ﷻ sent a fierce wind that devastated the enemy’s tents. The Confederates retreated without a major battle.
Lesson: Innovation and adaptation — even taking ideas from other cultures — is part of Islamic military strategy. Salman Al-Farisi brought a Persian idea, and the Messenger of Allah ﷺ adopted it because the idea was good and beneficial.
Fathu Makkah (8 AH / 630 CE) — A Bloodless Victory
Fathu Makkah was one of the cleanest military operations in human history.
Conditions:
| Side | Numbers | Situation |
|---|---|---|
| Muslims | 10,000 men | Entering Makkah from 4 directions |
| Quraysh | Unorganized | Unprepared, caught by surprise |
The Messenger of Allah ﷺ led 10,000 troops toward Makkah. He ﷺ could have destroyed Makkah — avenging 20 years of persecution, expulsion, and warfare waged by Quraysh against the Muslims.
Strategy of the Messenger of Allah ﷺ:
The Messenger of Allah ﷺ chose a surprising path: entering Makkah without bloodshed. He ﷺ divided the troops into 4 columns entering from different directions and gave very strict instructions:
“Do not fight except those who fight you.”
He ﷺ also announced a general amnesty:
مَا تَظُنُّونَ أَنِّي فَاعِلٌ بِكُمْ؟ قَالُوا: خَيْرًا، أَخٌ كَرِيمٌ وَابْنُ أَخٍ كَرِيمٍ. قَالَ: اذْهَبُوا فَأَنْتُمُ الطُّلَقَاءُ
“What do you think I will do with you?” They said: “Good. You are a noble brother and the son of a noble brother.” He ﷺ said: “Go, you are all free.” (HR. Muwatta Malik)
“You are all free” — After 20 years of being tortured, expelled, and fought against, the Messenger of Allah ﷺ granted amnesty to all of Quraysh. No retaliation. No mass executions. No plundering.
Result: Makkah fell without a major battle. There was only minor resistance at two points, handled without escalation. Quraysh embraced Islam en masse. The Ka’bah was cleansed of 360 idols.
Lesson: The greatest victory is not the one that kills the most enemies, but the one that changes the most enemy hearts. Forgiveness and mercy — when given from a position of strength — are weapons more powerful than the sword.
Table 8: Summary of Three Great Battles
| Battle | Year | Strength Ratio | Key Strategy | Result | Main Lesson |
|---|---|---|---|---|---|
| Badr | 2 AH | 1 : 3 | Strategic position + prayer | Total victory | Faith & strategy > numbers |
| Khandaq | 5 AH | 1 : 3.3 | Defensive trench | Enemy retreats | Innovation saves the Ummah |
| Fathu Makkah | 8 AH | Muslim dominance | General amnesty | Makkah without bloodshed | Forgiveness > revenge |
10. Conclusion: The Khilafah’s Military Is a Shield, Not a Tyrant’s Sword
After exploring 10 important points, let us summarize the essence of the Khilafah’s military system.
Amirul Jihad is the head of the defense department directly accountable to the Khalifah. He is not a political minister — he is an operational commander executing the Khalifah’s orders.
The military structure is very clear: the Khalifah as supreme commander, Amirul Jihad as executor, regular forces as the frontline, and reserve forces as a massive force in emergencies.
Military industry independence is not optional — it is an obligation. The Khilafah must not depend on other countries for defense, because dependence is a weakness that enemies can exploit.
Moral control over the military is the most distinguishing feature. The Khilafah’s military must not engage in politics, must not stage coups, and must not oppress the people. It is subordinate to Shariah and to the legitimate Khalifah.
The rules of war in Islam were established 1,400 years before the Geneva Conventions: no killing civilians, no destroying places of worship, no torturing prisoners, and no betrayal.
The Sirah of the Prophet ﷺ provides real examples that military victory is not about who kills the most, but who is closest to the help of Allah ﷻ — through faith, strategy, and character.
Summary of the Khilafah’s Military System
| Principle | Implementation |
|---|---|
| Command sovereignty | Khalifah as supreme commander |
| Professionalism | Trained regular forces + massive reserve forces |
| Independence | Domestic military industry, no foreign dependence |
| Shariah obedience | Military must not engage in politics, must not coup |
| Rules of war | Prohibition of killing civilians, destruction, torture, betrayal |
| Objective | Protecting Darul Islam + establishing global justice |
Allah ﷻ says:
وَلَيَنْصُرَنَّ اللَّهُ مَنْ يَنْصُرُهُ ۗ إِنَّ اللَّهَ لَقَوِيٌّ عَزِيزٌ الَّذِينَ إِنْ مَكَّنَّاهُمْ فِي الْأَرْضِ أَقَامُوا الصَّلَاةَ وَآتَوُا الزَّكَاةَ وَأَمَرُوا بِالْمَعْرُوفِ وَنَهَوْا عَنِ الْمُنْكَرِ ۗ وَلِلَّهِ عَاقِبَةُ الْأُمُورِ
“And Allah will surely support those who support Him. Indeed, Allah is Powerful and Exalted in Might. [And they are] those who, if We give them authority in the land, establish prayer and give zakah and enjoin what is right and forbid what is wrong. And to Allah belongs the outcome of [all] matters.” (QS. Al-Hajj [22]: 40-41)
“If We give them authority in the land” — Allah’s ﷻ help comes to those who support His religion. And one form of supporting the religion is building a strong, just, and moral defense. The Khilafah’s military is not an instrument of oppression — it is a manifestation of this verse: a force standing to establish prayer, give zakah, enjoin good, and forbid evil.
Dear readers, the world today is full of militaries that are strong but immoral, weapons that are sophisticated but directed at their own people, and defense budgets that are large but only protect regimes. The Khilafah offers something different: a military that is strong AND moral, weapons that are sophisticated AND dignified, defense that is large AND protects all people — Muslim and non-Muslim alike.
The question is not “is such a military possible?” — because the Sirah of the Prophet ﷺ already proved it 1,400 years ago. The question is: “when will the Muslim Ummah return to building the true shield?”
