FROM SAHIH BUKHARI - VOLUME 5, #637:
Narrated Buraida: The prophet sent Ali to Khalid to bring the Khumus (part of the war 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 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 Khumus."
ROM SAHIH BUKHARI - VOLUME 9, #506:
Narrated Abu Said Al-Khudri that during the battle with Bani Al-Mustaliq they (Muslims) captured some females and intended to have sexual relations with them without impregnating them. So they asked the prophet about coitus interruptus. The prophet said, "It is better that you should not do it, for Allah has written whom He is going to create till the Day of Resurrection".
Qaza'a said, "I heard Abu Said saying that the prophet said, "No soul is ordained to be created but Allah will create it.""
Narrated Abu Said Al-Khudri that while he was sitting with Allah's messenger we said, "Oh Allah's messenger, we got female captives as our booty, and we are interested in their prices, what is your opinion about coitus interruptus?" The prophet 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."
FROM THE HADITH OF THE SUNAN OF ABU DAWUD, VOLUME 2, # 2150:
Abu Said al-Khudri said: "The apostle of Allah 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 the apostle of Allah were reluctant to have intercourse with the female captives in the presence of their husbands who were unbelievers. So Allah, the Exalted, sent down the Quranic verse, "And all married women (are forbidden) unto you save those (captives) whom your right hands possess". That is to say, they are lawful for them when they complete their waiting period." [The Quran verse is 4:24].
FROM SAHIH MUSLIM, VOLUME 2, #3432
Abu Said al-Khudri reported that at the Battle of Hunain Allah's messenger sent an army to Autas and encountered the enemy and fought with them. Having overcome them and taken them captives, the Companions of Allah's messenger seemed to refrain from having intercourse with captive women because of their husbands being polytheists. Then Allah, Most High, sent down regarding that: "And women already married, except those whom your right hands possess (Quran - 4:24), (i.e. they were lawful for them when their Idda (menstrual) period came to an end).
We can conclude that the muslim soldiers, after winning a battle, were capturing women as a booty and they were having sex with them.
Some of you will say that it is not a rape, that the women were consenting to have sex with the muslim soldiers... But there is a problem:
Think about it from the women's point of view. A battle is fought and her side lost. Many of the husbands, fathers, and sons are now dead. Some have been captured. The women and children are also taken as captives. Imagine the horror of the females. Family members dead, homes and possessions are now gone, they are in the total power of their captors.
The captives are distributed amongst the Muslim men as slaves, husband and wife captives are separated. As soon as a female has her menstrual cycle her owner appears. He has been separated from his wife for a while out on the field of battle, sexually hungry, and he proceeds to have sex with his female slave.
Do you think that this female slave willingly has intercourse with him? Is that her wish? She has just experienced one of the most horrible events in her life, - the destruction of her tribe and family, the taking of her possessions, and being made someone's slave, and now she willing consents to have sex with the very men who brought this disaster upon her!? Of course not! What women would look upon with loving eyes the men that brought destruction upon her family and tribe!
