Sahih Muslim | Book 8 | Chapter 29

Narrated by Abu Sa'id al-Khudri (Allah her pleased with him)
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 be 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).

Narrated by Abu Sa'id al-Khudri (Allah be pleased with him)
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 possess out 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)
