Islamic Law strongly encourages, if not practically requires, the rape of female captives. A little background about Islamic law could be helpful in understanding what is going on.
The canonical Islamic Laws and scripture consists of Koran, Suna and Hadith. Bukhari would be the Hadith in this case.
It should be noted that Muhammad was considered the perfect man, the perfect example of behavior and it was stipulated that the laws of Islam are unchangeable. Muslims are stuck with this.
A quote from Ali Sina’s book “Understanding Muhammad”. p. 39, the section on rape, explains their Law. This is available in https://freerepublic.com/focus/f-news/4197848/posts, number 27. Post 28 and 29 are also relevant to understanding Palestinian and other Islamic sexual deviancy.
