Short answer: Yes. Islamic Sharia devotes a large part to slavery.
The Scripture of Muslims (Qur’an):
Quran 33:50–‘O Prophet, indeed We have made lawful to you your wives to whom you have given their due compensation and those your right hand possesses from what Allah has returned to you [of captives]’
Quran 23:5-6–‘And they who guard their private parts. Except from their wives or those their right hands possess, for indeed, they will not be blamed.
The Traditions of Muhammad (Hadith):
Sahih al-Bukhari 4200–‘Narrated Anas: The Prophet (ﷺ) offered the Fajr Prayer near Khaibar when it was still dark and then said, “Allahu-Akbar! Khaibar is destroyed, for whenever we approach a (hostile) nation (to fight), then evil will be the morning for those who have been warned.” Then the inhabitants of Khaibar came out running on the roads. The Prophet (ﷺ) had their warriors killed, their offspring and woman taken as captives. Safiya was amongst the captives, She first came in the share of Dahya Alkali but later on she belonged to the Prophet . The Prophet (ﷺ) made her manumission as her ‘Mahr’.’
Sahih al-Bukhari 4350–‘Narrated Buraida: The Prophet (ﷺ) sent `Ali to Khalid to bring the Khumus (of the booty) and I hated `Ali, and `Ali had taken a bath (after a sexual act with a slave-girl from the Khumus). I said to Khalid, “Don’t you see this (i.e. `Ali)?” When we reached the Prophet (ﷺ) I mentioned that to him. He said, “O Buraida! Do you hate `Ali?” I said, “Yes.” He said, “Do you hate him, for he deserves more than that from the Khumlus.”‘
Sahih al-Bukhari 5210–‘We got female captives in the war booty and we used to do coitus interruptus with them. So we asked Allah’s Messenger (ﷺ) about it and he said, “Do you really do that?” repeating the question thrice, “There is no soul that is destined to exist but will come into existence, till the Day of Resurrection.”
Sahih al-Bukhari 2229–‘Narrated Abu Sa`id Al-Khudri: that while he was sitting with Allah’s Messenger (ﷺ) he said, “O Allah’s Messenger (ﷺ)! We get female captives as our share of booty, and we are interested in their prices, what is your opinion about coitus interrupt us?” The Prophet (ﷺ) said, “Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence.’
Sunan Abi Dawud 2155–‘Abu Sa’id Al Khudri said “The Apostle of Allaah(ﷺ) sent a military expedition to Awtas on the occasion of the battle of Hunain. They met their enemy and fought with them. They defeated them and took them captives. Some of the Companions of Apostle of Allaah (ﷺ) were reluctant to have relations with the female captives because of their pagan husbands. So, Allaah the exalted sent down the Qur’anic verse “And all married women (are forbidden) unto you save those (captives) whom your right hand posses.” This is to say that they are lawful for them when they complete their waiting period.’
Sunan Abi Dawud 4473–‘Narrated Ali ibn AbuTalib: A slave-girl belonging to the house of the Messenger of Allah (ﷺ) committed fornication. He (the Prophet) said: Rush up, Ali, and inflict the prescribed punishment on her. I then hurried up, and saw that blood was flowing from her, and did not stop. So I came to him and he said: Have you finished inflicting (punishment on her)? I said: I went to her while her blood was flowing. He said: Leave her alone till her bleeding stops; then inflict the prescribed punishment on her. And inflict the prescribed punishment on those whom your right hands possess (i.e. slaves).’
Sahih al-Bukhari 2592–‘Narrated Kuraib: the freed slave of Ibn `Abbas, that Maimuna bint Al-Harith told him that she manumitted a slave-girl without taking the permission of the Prophet. On the day when it was her turn to be with the Prophet, she said, “Do you know, O Allah’s Messenger (ﷺ), that I have manumitted my slave-girl?” He said, “Have you really?” She replied in the affirmative. He said, “You would have got more reward if you had given her (i.e. the slave-girl) to one of your maternal uncles.”‘
Sahih al-Bukhari 2141–‘Narrated Jabir bin `Abdullah: A man decided that a slave of his would be manumitted after his death and later on he was in need of money, so the Prophet (ﷺ) took the slave and said, “Who will buy this slave from me?” Nu’aim bin `Abdullah bought him for such and such price and the Prophet (ﷺ) gave him the slave.’
Sahih Muslim 1602–‘Jabir (Allah be pleased with him) reported: There came a slave and pledged allegiance to Allah’s Apostle (ﷺ) on migration; he (the Holy Prophet) did not know that he was a slave. Then there came his master and demanded him back, whereupon Allah’s Apostle (ﷺ) said: Sell him to me. And he bought him for two black slaves, and he did not afterwards take allegiance from anyone until he had asked him whether he was a slave (or a free man)’
Sahih Muslim 1755–‘..Some of the enemies were killed and some were taken prisoners. I saw a group of persons that consisted of women and children. I was afraid lest they should reach the mountain before me, so I shot an arrow between them and the mountain. When they saw the arrow, they stopped. So I brought them, driving them along. Among them was a woman from Banu Fazara. She was wearing a leather coat. With her was her daughter who was one of the prettiest girls in Arabia. I drove them along until I brought them to Abu Bakr who bestowed that girl upon me as a prize.‘
Sunan Abi Dawud 3009–‘Anas bin Malik said “The Apostle of Allaah(ﷺ) attacked Khaibar and we captured it by conquest. He then gathered the captives of war.”’
Bulugh al-Maram 11:1307–‘Nafi’ (RAA) narrated, ‘The Messenger of Allah (ﷺ) made an attack on Bani al-Mustaliq when they were unaware. He killed the men who were lighting and took the women and children as captives.’’
Sahih al-Bukhari 4138–‘Narrated Ibn Muhairiz: I entered the Mosque and saw Abu Sa`id Al-Khudri and sat beside him and asked him about Al-Azl (i.e. coitus interruptus). Abu Sa`id said, “We went out with Allah’s Messenger (ﷺ) for the Ghazwa of Banu Al-Mustaliq and we received captives from among the Arab captives and we desired women and celibacy became hard on us and we loved to do coitus interruptus. So when we intended to do coitus interrupt us, we said, ‘How can we do coitus interruptus before asking Allah’s Messenger (ﷺ) who is present among us?” We asked (him) about it and he said, ‘It is better for you not to do so, for if any soul (till the Day of Resurrection) is predestined to exist, it will exist.”‘
Sunan Abi Dawud 4404–‘Narrated Atiyyah al-Qurazi: I was among the captives of Banu Qurayzah. They (the Companions) examined us, and those who had begun to grow hair (pubes) were killed, and those who had not were not killed[they were taken captives]. I was among those who had not grown hair.’
Sahih al-Bukhari 947–‘Narrated Anas bin Malik: Allah’s Messenger (ﷺ) (p.b.u.h) offered the Fajr prayer when it was still dark, then he rode and said, ‘Allah Akbar! Khaibar is ruined. When we approach near to a nation, the most unfortunate is the morning of those who have been warned.” The people came out into the streets saying, “Muhammad and his army.” Allah’s Messenger (ﷺ) vanquished them by force and their warriors were killed; the children and women were taken as captives. Safiya was taken by Dihya Al-Kalbi and later she belonged to Allah’s Apostle go who married her and her Mahr was her manumission.’
Sahih al-Bukhari 4121–‘…the Prophet (ﷺ) said to the Ansar, “Get up for your chief or for the best among you.” Then the Prophet (ﷺ) said (to Sa`d).” These (i.e. Banu Quraiza) have agreed to accept your verdict.” Sa`d said, “Kill their (men) warriors and take their offspring as captives, “On that the Prophet (ﷺ) said, “You have judged according to Allah’s Judgment,” or said, “according to the King’s judgment.”‘
Sahih al-Bukhari 371–‘We conquered Khaibar, took the captives, and the booty was collected. Dihya came and said, ‘O Allah’s Prophet! Give me a slave girl from the captives.’ The Prophet said, ‘Go and take any slave girl.”
Sahih Muslim 1438 a–‘Abu Sirma said to Abu Sa’id al Khadri (Allah he pleased with him): Abu Sa’id, did you hear Allah’s Messenger (ﷺ) mentioning al-‘azl? He said: Yes, and added: We went out with Allah’s Messenger (ﷺ) on the expedition to the Bi’l-Mustaliq and took captive some excellent Arab women; and we desired them, for we were suffering from the absence of our wives, (but at the same time) we also desired ransom for them. So we decided to have sexual intercourse with them but by observing ‘azl (Withdrawing the male sexual organ before emission of semen to avoid-conception). But we said: We are doing an act whereas Allah’s Messenger is amongst us; why not ask him? So we asked Allah’s Messenger (ﷺ), and he said: It does not matter if you do not do it, for every soul that is to be born up to the Day of Resurrection will be born.’
Ibn Qayyim al-Jawziyya (p.160)–‘”Muhammad had many male and female slaves. He used to buy and sell them, but he purchased more slaves then he sold. He once sold one black slave for two. His purchases of slaves were more than he sold. Muhammad had a number of black slaves. One of them was named ‘Mahran’. Muhammad forced him to do more labor than the average man. Whenever Muhammad went on a trip and he, or his people, got tired of carrying their stuff, he made Mahran carry it. Mahran said “Even if I were already carrying the load of 6 or 7 donkeys while we were on a journey, anyone who felt weak would throw his clothes or his shield or his sword on me so I would carry that, a heavy load”. Tabari and Jawziyya both record this, so Islam accepts this as true.”
Sirat Rasulallah (p.466)–“Then the apostle divided the property, wives, and children of Banu Qurayza among the Muslims…then the apostle sent Sa’d Zayd brother of Ashhal with some of the captive women of Banu Qurayza to Najd and he sold them for horse and weapons.”
Saudi Sheikh Saleh Al-Fawzan, a member of the Senior Council of Clerics–“Slavery is a part of Islam…(those who argue that slavery is abolished are) ignorant, not scholars. They are merely writers. Whoever says such things is an infidel.”
A Former Muslim Notes:
The Quran and Hadith contain many prescriptive commands and traditions about slavery. The fact is the prophet of Allah had many slaves, he bought and sold slaves; he had sex with slaves; he captured many slaves, and gave slaves to his minions (followers).
Liberal Muslims don’t pay heed to these references. They only assume that Islam has nothing to do with slavery. For example, Shehzad Saleem, director of the Institute of Islamic Studies in Pakistan states, “Among many other misconceptions about Islam is the notion that it gives sanction to slavery and permits its followers to enslave prisoners of war, particularly women and establish extra-marital relations with them. We strongly affirm that Islam has not the slightest link with slavery and concubinage. On the contrary, it completely forbids these practices.”
I don’t know what to think of Shehzad’s statement. Should I consider it taqiyya (lying) or is he just ignorant?
