1. History

During his life, Muhammad made it the responsibility of the Islamic government to provide food and clothing, on a reasonable basis, to captives, regardless of their religion.Template:Additional citation If the prisoners were in the custody of a person, then the responsibility was on the individual.^[1]Template:Additional citation

Historically, Muslims routinely captured large number of prisoners. Aside from those who converted to Islam, most were ransomed or enslaved.^[2] Pasquier writes,

It was the custom to enslave prisoners of war and the Islamic state would have put itself at a grave disadvantage vis-a-vis its enemies had it not reciprocated to some extent. By guaranteeing them [male POWs] humane treatment, and various possibilities of subsequently releasing themselves, it ensured that a good number of combatants in the opposing armies preferred captivity at the hands of Muslims to death on the field of battle.^[3]

According to accounts written by Muhammad's followers, after the Battle of Badr, some prisoners were executed for their earlier crimes in Mecca,Template:Additional citation but the rest were given options: They could convert to Islam and thus win their freedom; they could pay ransom and win their freedom; they could teach 10 Muslims to read and write and thus win their freedom.^[4] William Muir wrote of this period:

In pursuance of Mahomet's commands, the citizens of Medîna, and such of the Refugees as possessed houses, received the prisoners, and treated them with much consideration. “Blessings be on the men of Medina!” said one of these prisoners in later days; “they made us ride, while they themselves walked: they gave us wheaten bread to eat when there was little of it, contenting themselves with dates.”^[5]

—William Muir, The Life of Mahomet

During his rule, Caliph Umar made it illegal to separate related prisoners of war from each other, after a captive complained to him for being separated from her daughter.^[6]Template:Additional citation

These principles were also honoured during the Crusades, as exemplified by sultans such as SaladinTemplate:Additional citation and al-Kamil. For example, after al-Kamil defeated the Franks during the Crusades, Oliverus Scholasticus praised the Islamic laws of war, commenting on how al-Kamil supplied the defeated Frankish army with food:^[7]Template:Additional citation

Who could doubt that such goodness, friendship and charity come from God? Men whose parents, sons and daughters, brothers and sisters, had died in agony at our hands, whose lands we took, whom we drove naked from their homes, revived us with their own food when we were dying of hunger and showered us with kindness even when we were in their power."^[8]

Al-Qardawai, an Egyptian Muslim scholar born in 1926, adds in light of the verses below ^{[Quran 4:75-76]}, that the Islamic state should go to war to rescue non-Muslim minorities if they require help of the state and if the Islamic state is able to rescue them:

Would not you fight in the way of God for al-mustad‛afīn (the oppressed socially weak Muslims) from men, women and children who pray: Our Lord! Take us from this city of the oppressive people and appoint for us from Your side a guardian and appoint for us from Your side a protector. Those who have believed fight in the way of God and those who disbelieve fight in the way of Satan, so fight the allies of Satan; surely the plot of Satan is weak.^{[Quran 4:75-76][9]}

2. Treatment of Prisoners

Upon capture, the prisoners must be guarded and not ill-treated.^[10] Islamic law holds that the prisoners must be fed and clothed, either by the Islamic government or by the individual who has custody of the prisoner. This position is supported by the verse ^{[Quran 76:8]} of the Quran. The prisoners must be fed in a dignified manner, and must not be forced to beg for their subsistence.^[11] Muhammad's early followers also considered it a principle to not separate prisoners from their relatives.^[6]

After the fighting is over, prisoners are to be released freely, with some prospect of survival, or exchanged. The prisoners are not to be forced to convert to Islam.^[12] The freeing or ransoming of prisoners by Muslims themselves is highly recommended as a charitable act.^[10] The Qur'an also urges kindness to captives^[13] and recommends, their liberation by purchase or manumission. The freeing of captives is recommended both for the expiation of sins^[14] and as an act of simple benevolence.^[15][16] However, the Quran also permits certain forms of punishments against certain captives, such as those who are deemed as waging war against Islam, disbelievers, adulterers and fornicators.^[17]

2.1. Women and Children

According to the authentication of Muslim scholars, women and children prisoners of war cannot be killed under any circumstances, regardless of their faith,^[2] but that they may be enslaved, freed or ransomed. Women who are neither freed nor ransomed by their people were to be kept in bondage and referred to as ma malakat aymanukum (slaves) to give them their rights to survive peacefully, and they could not be left astray.

Some modern Islamic extremist groups have taken slaves, including women and children. Abubakar Shekau, the leader of Boko Haram, a Nigerian extremist group, said in an interview, "I shall capture people and make them slaves" when claiming responsibility for the 2014 Chibok kidnapping.^[18] Shekau has justified his actions by appealing to the Quran saying "[w]hat we are doing is an order from Allah, and all that we are doing is in the Book of Allah that we follow".^[19] In October 2014, in its digital magazine Dabiq, ISIL explicitly claimed religious justification for enslaving Yazidi women. Specifically, ISIL argued that the Yazidi were idol worshipers and justified the sexual slavery of the captured non-muslim victims as a permissible manner of enjoying the spoils of war.^{[20][21][22][23][24][25]} ISIL appealed to apocalyptic beliefs and "claimed justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world."^{[26][27][28][29][30][31]}

2.2. Men

One traditional opinion holds that executing prisoners of war is strictly forbidden; this is the most widely accepted view, and one upheld by the Hanafi madhab.^[32]

However, the opinion of the Maliki, Shafi'i, Hanbali and Jafari madhabs is that adult male prisoners of war may be executed.^[33] The decision for an execution is to be made by the Muslim leader. This opinion was also held by the Muslim judge, Sa'id bin Jubair (665-714 AD) and Abu Yusuf, a classical jurist from the Hanafi school of jurisprudence.^[34] El Fadl argues that Muslim jurists adopted this position largely because it was consistent with the war practices of the Middle Ages.^[32] Muhammad Hamidullah, while reminding that execution in such cases was exceptional and depending on many factors, further states that beheading was discouraged: "unanimity was reached among the Companions of the Prophet not to behead prisoners of war. In short, capital punishment for prisoners of war is only permissible in extreme cases of necessity and in the higher interests of the State."^[35]

Most contemporary Muslim scholars prohibit altogether the killing of prisoners and hold that this was the policy practiced by Muhammad.^[36] The 20th-century Muslim scholar, Sayyid Abul Ala Maududi states that no prisoner should be "put to the sword" in accordance with a saying of Muhammad.^[37]

Yusuf Ali, another 20th-century Muslim scholar, while commenting on verse ^[Quran 9:6], writes,

Even those the enemies of Islam, actively fighting against Islam, there may be individuals who may be in a position to require protection. Full asylum is to be given to them, and opportunities provided for hearing the Word of Allah...If they do not see their way to accept Islam, they will require double protection: (1) from the Islamic forces openly fighting against their people, and (2) from their own people, as they detached themselves from them. Both kinds of protection should be ensured for them, and they should be safely escorted to a place where they can be safe.^[38]

Maududi further states that Islam forbids torturing, especially by fire, and quotes Muhammad as saying, "Punishment by fire does not behoove anyone except the Master of the Fire [God]."^[37]

Quoting from the sources, Muhammad Munir, from the Department of Law of the International Islamic University, Pakistan , says that early religious authorities standing against the execution of POWs at all include 'Ali b. Abi Tãlib, Al-Hasan b. al-Hasan al-Basrl (d. 110/728), Hammãd b. Abi Sulaymän (d. 120/737), Muhammad b. Sirin (d. 110/728), Mujãhid b. Jabr (d. 103/721), 'Abd al-Mãlik b. 'Abd al-'Azïz b. Jurayj (d. 150/767), 'Atâ' b. Abi Rabãh (d. 114/732) and Abû 'Ubayd ibn Sallãm,^[39] while later scholars favouring the same opinion include Muhammad b. Ahmad al-Qurtubl (d. 671/1272), who cites ^{[Quran 47:4]} in proposing the impossibility of execution if the letter of the Qur'an is followed.^[40] Ibn Rushd (d. 594/1198) is also quoted: "[A] number of jurists did not permit executing the prisoners of war. Al-Hasan b. Muhammad al-Tamïmï (d. 656/1258) stated consensus (ijma) of the Companions on this view."^[41] He further shows that the rare executions were more due to the crimes they committed before the captivity than their status of POW itself. A well known case which is relevant in this regard is that of 'Abd Allah b. Khatal, who was one of the few people who were not granted immunity at the conquest of Mecca. A group of people "could have been punished by a tribunal should there have been one at the time”. But he was the only one executed for what we would today call high treason (as he collected tax money from Muslims before defecting and fighting them).^[42] More generically, he also shows that "in the first one hundred years of Islamic military history, that is, from the time of the Prophet (peace be upon him) till the time of Caliph 'Umar b. 'Abdul 'Aziz, there were only six or seven such cases, even if we were to accept the spurious reports of such executions."
