Abu Saeed Khudri reported,
On the day of Hunayn, the Messenger of Allah ﷺ sent an army to Awtas. They met an enemy force and fought them, prevailing over them and capturing female prisoners. Some of the companions of the Messenger of Allah ﷺ felt uneasy about having relations with these women because of their husbands among the polytheists. So Allah 
revealed concerning this, "And married women, except those your right hands possess" [Nisa 4:24], meaning they are lawful for you once their waiting period has ended.

Sahihعن أبي سعيد الخدري
أن رسول الله ﷺ يوم حنين بعث جيشا إلى أوطاس، فلقوا عدوا فقاتلوهم، فظهروا عليهم، وأصابوا لهم سبايا، فكأن ناسا من أصحاب رسول الله ﷺ تحرجوا من غشيانهن من أجل أزواجهن من المشركين، فأنزل الله عز وجل في ذلك {والمحصنت من النساء إلا ما ملكت أيمنكم} [النساء: ٢٤] أي فهن لكم حلال إذا انقضت عدتهن.
