Muslim Allah abrogates the marriage of female non-Muslim captives to their non-Muslim husbands so they can have sex with their Muslim captors. Truly Allah is merciful, compassionate.
Chapter 29: IT IS PERMISSIBLE TO HAVE SEXUAL INTERCOURSE WITH A CAPTIVE WOMAN AFTER SHE IS PURIFIED (OF MENSES OR DELIVERY) IN CASE SHE HAS A HUSBAND, HER MARRIAGE IS ABROGATED AFTER SHE BECOMES CAPTIVE
Sahih Muslim Book 008, Number 3432:
Abu Sa’id al-Khudri (Allah her pleased with him) reported that at the Battle of Hanain Allah’s Messenger (may peace be upon him) 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 (may peace te upon him) 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 (iv. 24)" (i. e. they were lawful for them when their 'Idda period came to an end).
Sahih Muslim Book 008, Number 3433:
Abu Sa’id al-Khudri (Allah be pleased with him) reported that Allah’s Apostle (may peace be upon him) sent a small army. The rest of the hadith is the same except this that he said: Except what your right hands possessout of them are lawful for you; and he did not mention" when their 'idda period comes to an end". This hadith has been reported on the authority of AbuSa’id (al-Khudri) (Allah be pleased with him) through another chain of transmitters and the words are: They took captives (women) on the day of Autas who had their husbands. They were afraid (to have sexual intercourse with them) when this verse was revealed:" And women already married except those whom you right hands posses" (iv. 24)
The relevant verse is 4:24
Malik Also forbidden for you are married women, except those who have fallen in your hands as prisoners of war. This is the order of Allah relating to marriage prohibitions. All women other than these are lawful provided you seek them in marriage with gifts from your property (dowry), desiring chastity and not lust. Give them their dowry as an obligation for the benefit you have received from your marriage relationship. However, there is no blame on you if you change the agreement of dowry with mutual consent. Allah is the Knowledgeable, Wise.
