Top 18 Prophet Muhammad’s Rules of War

The Prophet Muhammad’s rules of war are a cornerstone of Islamic ethics and international humanitarian principles. These rules were introduced to limit harm, protect the innocent, and ensure that even in conflict, morality remained central. They demonstrate the Prophet’s commitment to justice, compassion, and the preservation of human dignity.

Below are the rules of war taught and implemented by Prophet Muhammad ﷺ, organized for clarity and SEO effectiveness.

1. Do Not Kill Women

Prophet Muhammad ﷺ strictly forbade the killing of women during war because they are non-combatants who do not participate in fighting. This rule is one of the clearest and most well-documented principles in Islamic warfare.

Several authentic narrations (ahadith) support this rule:

Ibn ‘Umar (رضي الله عنه) reported:

“A woman was found killed in one of the battles, and the Messenger of Allah ﷺ forbade killing women and children.”
Sahih al-Bukhari (3014) and Sahih Muslim (1744)

“وُجِدَتِ امْرَأَةٌ قُتِلَتْ فِي غَزْوَةٍ فَنَهَى رَسُولُ اللَّهِ ﷺ عَن قَتْلِ النِّسَاءِ وَالأَطْفَالِ.”

This is one of the strongest and most direct pieces of evidence.

“The Messenger of Allah ﷺ saw a slain woman in one of the battles and said: ‘She was not fighting.’”

“فَرَأَى رَسُولُ اللَّهِ ﷺ امْرَأَةً قُتِلَتْ فِي غَزْوَةٍ فَقَالَ: لَمْ تَكُنْ تُقَاتِلُ.”
Sunan Abu Dawood (2669)

This narration shows the reasoning behind the rule:
Women were not fighters, so harming them was absolutely forbidden.

2. Do Not Kill Children

Prophet Muhammad ﷺ strictly forbade killing children in warfare. Children are innocent non-combatants and must be protected in all circumstances.

Ibn ‘Umar (رضي الله عنه) said:

“A woman was found killed in one of the battles, and the Messenger of Allah ﷺ forbade killing women and children.”

“وُجِدَتِ امْرَأَةٌ قُتِلَتْ فِي غَزْوَةٍ فَنَهَى رَسُولُ اللَّهِ ﷺ عَن قَتْلِ النِّسَاءِ وَالأَطْفَالِ.”
Sahih al-Bukhari (3014), Sahih Muslim (1744)

This hadith explicitly mentions children, showing a clear prohibition.

3. Do Not Kill the Elderly

The elderly were also protected under the rules of war established by the Prophet Muhammad ﷺ.

When sending out military leaders, the Prophet ﷺ gave clear commands:

“Do not kill a woman, a child, or an old man.”

“لَا تُقْتَلُوا النِّسَاءَ وَالأَطْفَالَ وَالشُّيُوخَ.”
Musnad Ahmad (20172)
Sunan al-Bayhaqi (17989)

This direct instruction includes old men (الشيوخ), showing that they were not to be attacked because they were generally non-combatants.

4. Do Not Kill Monks or Religious Clergy

Monks, priests, and other religious figures were given special protection because they lived in worship and were not fighters.

When the Prophet ﷺ dispatched armies, he instructed them to avoid harming religious clergy:

“You will find monks secluded in monasteries; leave them and what they worship.”

“سَتَجِدُونَ الرُّهُوبِيِّينَ مُنْعَزِلِينَ فِي دِيَارِهِمْ؛ فَاتْرُكُوهُمْ وَمَا يَعْبُدُونَ.”

Reported by Ibn ‘Abbas in Musnad al-Bazzar and Tabarani’s al-Kabir

The first Caliph, Abu Bakr (رضي الله عنه), following the Prophet’s teachings, told the army:

5. Do Not Destroy Trees

Prophet Muhammad ﷺ established a unique environmental ethic in warfare: Muslim armies were not allowed to destroy trees—especially fruit-bearing ones. This principle protected both nature and civilian food sources. Although many of these instructions were preserved through the commands of the early caliphs, they were directly based on the Prophet’s own teachings.

When Abu Bakr (رضي الله عنه), following the Prophet ﷺ, sent out the army of Usama ibn Zayd, he said:

“وَلَا تَقْطَعُوا نَخْلًا وَلَا تُحْرِقُوهُ، وَلَا تَقْطَعُوا شَجَرًا مُثْمِرًا…”
al-Tabari, Tarikh (4/234)

“Do not cut down or burn palm trees, and do not cut down fruit-bearing trees…”

This reflects the Prophet Muhammad’s exact rules of war, showing his emphasis on preserving creation even in times of conflict.

6. Do Not Burn or Destroy Homes

Another major rule established by Prophet Muhammad ﷺ is the prohibition of burning or destroying homes or inhabited buildings. Civilian structures were protected, and unnecessary destruction was strictly forbidden.

The Prophet ﷺ laid down general rules when sending armies:

“انْطَلِقُوا بِاسْمِ اللهِ… وَلَا تَغُلُّوا، وَلَا تُمَثِّلُوا، وَلَا تَقْتُلُوا وَلِيدًا…”
Sahih Muslim (1731)

“Go forth in the name of Allah… Do not act treacherously, do not mutilate, and do not kill a child…”

This hadith outlines the moral foundation: no treachery, no cruelty, no harm to civilians—including destruction of their homes.

Abu Bakr (رضي الله عنه), applying the Prophet’s teachings directly to warfare, said:

“وَلَا تُخَرِّبُوا عَامِرًا”
al-Tabari, Tarikh (4/234)

“Do not destroy any inhabited places.”

This demonstrates a consistent Islamic rule across both the Prophetic and caliphate eras.

7. Do Not Destroy Crops

Prophet Muhammad ﷺ prohibited destroying crops because doing so harms innocent civilians and leads to starvation. Crops are necessary for life, so they must be protected.

This rule appears clearly in the early Islamic military codes based on the Prophet’s teachings. Abu Bakr said to the Muslim army:

“وَلَا تَقْطَعُوا شَجَرًا مُثْمِرًا، وَلَا تَدُكُّوا الزُّرُوعَ…”
al-Tabari, Tarikh (4/234)

“Do not cut down fruit-bearing trees, and do not destroy crops.”

Islamic jurists later emphasized that this rule comes directly from the Prophet’s own method of war, where he protected civilian resources and forbade unnecessary destruction.

8. Do Not Kill Animals Except for Necessity

The Prophet Muhammad ﷺ also forbade killing animals during war except when needed for food. Animals were not to be harmed to create economic loss or instill fear.

The Prophet ﷺ taught the sanctity of animal life even outside war:

“مَا مِنْ إِنْسَانٍ يَقْتُلُ عُصْفُورًا فَمَا فَوْقَهَا بِغَيْرِ حَقِّهَا إِلَّا سَأَلَهُ اللهُ عَنْهَا يَوْمَ الْقِيَامَةِ.”
Sunan al-Nasa’i (4348)

“There is no person who kills a sparrow or anything larger without right except that Allah will ask him about it on the Day of Judgment.”

And when Abu Bakr repeated the Prophet’s method to the army of Usama:

“وَلَا تَذْبَحُوا شَاةً وَلَا بَعِيرًا إِلَّا لِمَأْكَلَةٍ”
  al-Tabari (4/234)

“Do not slaughter sheep or camels except for food.”

9. Do Not Mutilate Bodies

This rule preserved livestock and ensured that animals were only taken when genuinely necessary.

One of the clearest Prophet Muhammad rules of war is the strict prohibition of mutilating bodies. Mutilation—cutting or disfiguring a body—was common in pre-Islamic wars, but Prophet Muhammad ﷺ completely forbade it to preserve human dignity even after death.

The Prophet ﷺ said:

“انْطَلِقُوا بِاسْمِ اللهِ… وَلَا تُمَثِّلُوا…”
Sahih Muslim (1731)

“Go forth in the name of Allah… and do not mutilate (the dead)…”

This direct command is part of the Prophet’s official instructions to military leaders.

Islamic scholars agree that mutilation is haram (forbidden) in all cases, including warfare.

10. Do Not Betray or Act Treacherously

Prophet Muhammad ﷺ emphasized honesty and integrity even during war, banning all forms of treachery, deception, or betrayal of agreements.

The Prophet ﷺ said:

“وَلَا تَغُلُّوا…”
Sahih Muslim (1731)

“Do not act treacherously…”

Another hadith states:

“إِنَّ الْغَادِرَ يُنْصَبُ لَهُ لِوَاءٌ يَوْمَ الْقِيَامَةِ”
Sahih Muslim (1738)

“The treacherous person will have a banner raised for him on the Day of Judgment.”

This shows the seriousness of betrayal in Islam.

11. Do Not Start Hostilities

Islam commands that war must never be initiated aggressively. Muslims are only allowed to fight in self-defense, not as aggressors.

“وَقَاتِلُوا فِي سَبِيلِ اللهِ الَّذِينَ يُقَاتِلُونَكُمْ وَلَا تَعْتَدُوا ۚ إِنَّ اللهَ لَا يُحِبُّ الْمُعْتَدِينَ”
Surah Al-Baqarah 2:190

“Fight in the way of Allah those who fight you, but do not transgress. Indeed, Allah does not love the aggressors.”

The Prophet ﷺ never initiated aggression and always warned against starting hostilities.

He said:

“لَا تَتَمَنَّوْا لِقَاءَ الْعَدُوِّ…”
Sahih al-Bukhari (2966)

“Do not wish to meet the enemy…”

This teaches Muslims to avoid conflict unless it becomes absolutely necessary.

12. Provide Safe Passage for Those Who Request Protection

A unique aspect of the Prophet Muhammad’s rules of war is the requirement to grant safety and shelter to anyone—even an enemy—who seeks protection.

“وَإِنْ أَحَدٌ مِنَ الْمُشْرِكِينَ اسْتَجَارَكَ فَأَجِرْهُ حَتَّى يَسْمَعَ كَلَامَ اللهِ ثُمَّ أَبْلِغْهُ مَأْمَنَهُ”
Surah At-Tawbah 9:6

“And if any of the polytheists seeks your protection, then grant him protection so that he may hear the word of Allah; then escort him to a place of safety.”

In the Treaty of Hudaybiyyah, multiple individuals sought refuge with the Muslims, and the Prophet ﷺ honored every agreement and ensured safe treatment.

This humanitarian rule is now reflected in modern international law—yet Islam established it 1400 years ago.

13. Treat Prisoners of War with Kindness

Prophet Muhammad ﷺ established unprecedented ethical standards in dealing with prisoners of war. At a time when captives were often mistreated, enslaved, or deprived, the Prophet commanded Muslims to treat them with dignity and compassion. 

The Qur’an praises those who “give food, out of love for Him, to the needy, the orphan, and the captive,” highlighting that kindness to prisoners is an act of faith. During the Battle of Badr, the Prophet instructed his companions to ensure that prisoners were fed from the best food available—sometimes even receiving better meals than their captors.

This demonstrated that justice and mercy apply even toward one’s enemies. His example showed the world that true strength lies not in domination, but in maintaining humanity and moral integrity even in times of conflict.

14. Honor Agreements and Peace Treaties

Honoring promises and maintaining the sanctity of agreements were fundamental principles emphasized by Prophet Muhammad ﷺ. He consistently upheld treaties—whether with allies, tribes, or even former adversaries—and commanded Muslims never to betray trust or break a pact. 

The Treaty of Hudaybiyyah is a powerful example: despite some terms seeming unfavorable, the Prophet abided strictly by its clauses, teaching the community that integrity and reliability form the backbone of a just society. 

This commitment to peaceful resolution and mutual respect laid the foundations for ethical diplomacy in Islam. Through his actions, the Prophet demonstrated that fulfilling agreements is not merely a legal obligation but a moral duty that reflects sincerity, honor, and the true spirit of faith.

15. Do Not Attack Those Who Withdraw from Battle

One of the clear rules of war of the Prophet Muhammad is that Muslims are strictly forbidden from attacking enemies who retreat or surrender. Once an opposing combatant lays down arms, flees, or clearly indicates withdrawal from the fight, they are considered non-combatants and must not be harmed. 

This rule emphasizes the Prophet’s commitment to justice and humane conduct during conflict, ensuring that warfare does not become an excuse for revenge or indiscriminate killing.

The Prophet ﷺ instructed his commanders:

“لا تُقَاتِلُوا مَنْ تَرَكَ أَسْلِحَتَهُ”
Reported in Musnad Ahmad

“Do not fight anyone who has laid down his weapons.”

This teaching was applied during many campaigns. For example, during the Battle of Khaybar and other expeditions, prisoners who surrendered or tribes who sought peace were not attacked, and safe conduct was provided according to the Prophet’s instructions.

16. Fight Only Combatants

A core principle in the Prophet Muhammad’s rules of war is that Muslims are only allowed to fight actual combatants—those actively participating in hostilities. Civilians, bystanders, and non-combatants are strictly protected. 

This rule ensures that warfare does not become indiscriminate and emphasizes the importance of moral responsibility, even during armed conflict.

The Prophet ﷺ instructed:

“لا تُقاتِلُوا النَّاسَ حَتَّى يَقاتِلُوكُمْ”
Reported in Musnad Ahmad

“Do not fight people until they fight you.”

This was also reinforced during the Prophet’s campaigns, where women, children, the elderly, and non-combatant workers were consistently spared, reflecting a strict ethical framework for engagement in battle.

17. Do Not Force Anyone to Convert to Islam

Prophet Muhammad ﷺ made it clear that faith is a matter of personal choice, and no one should be coerced into accepting Islam. Forced conversion was strictly prohibited, even in the context of war, ensuring that religious freedom remained protected.

“لَا إِكْرَاهَ فِي الدِّينِ قَد تَّبَيَّنَ الرُّشْدُ مِنَ الْغَيِّ”
Surah Al-Baqarah 2:256

“There is no compulsion in religion. The right path has become clear from the wrong.”

Even after battles where Muslims were victorious, captives and opponents were never forced to adopt Islam. The Prophet ﷺ respected their freedom of belief, emphasizing moral persuasion rather than coercion.

18. Uphold Justice Even Against the Enemy

One of the most important rules of war is the command to maintain justice and fairness, even when dealing with one’s enemies. Islam forbids oppression, revenge, or any form of injustice, emphasizing that ethical conduct must be preserved regardless of the circumstances. 

This principle ensures that the battlefield does not become a place of unchecked cruelty and that human dignity is always respected.

“يَا أَيُّهَا الَّذِينَ آمَنُوا كُونُوا قَوَّامِينَ بِالْقِسْطِ شُهَدَاءَ لِلَّهِ وَلَوْ عَلَى أَنفُسِكُمْ أَوِ الْوَالِدَيْنِ وَالأَقْرَبِينَ”
Surah An-Nisa 4:135

“O you who have believed, be persistently standing firm in justice, witnesses for Allah, even if it be against yourselves or your parents and relatives.”

The Prophet ﷺ said:

“إِنَّ الْمُسْلِمِينَ لَا يُظْلَمُونَ وَلَا يَظْلِمُونَ”

Sahih Muslim (2564)

“The Muslims neither oppress nor are oppressed.”

Even during battle, the Prophet ﷺ instructed that ethical rules must be followed. Commanders were told to avoid transgressions and to ensure justice, even toward enemies who may have acted unjustly first. Upholding justice, even in war, distinguishes Islamic ethics from indiscriminate or revenge-driven warfare.
