It has been narrated on the authority of Salama (b. al-Akwa') who said

We fought against the Fazara, and Abu Bakr was the commander over us. He had been appointed by the Messenger of Allah (ﷺ). When we were only at an hour's distance from the water of the enemy, Abu Bakr ordered us to attack. We made a halt during the last part of the night to rest and then we attacked from all sides and reached their watering-place where a battle was fought. Some of the enemies were killed and some were taken prisoners. I saw a group of persons that consisted of women and children. I was afraid lest they should reach the mountain before me, so I shot an arrow between them and the mountain. When they saw the arrow, they stopped. So I brought them, driving them along. Among them was a woman from Banu Fazara. She was wearing a leather coat. With her was her daughter who was one of the prettiest girls in Arabia. I drove them along until I brought them to Abu Bakr who bestowed that girl upon me as a prize. So we arrived in Medina. I had not yet disrobed her when the Messenger of Allah (ﷺ) met me in the street and said: Give me that girl, O Salama. I said: Messenger of Allah, she has fascinated me. I had not yet disrobed her. When on the next day the Messenger of Allah (ﷺ) again met me in the street, he said: O Salama, give me that girl, may Allah bless your father. I said: She is for you, Messenger of Allah! By Allah. I have not yet disrobed her. The Messenger of Allah (ﷺ) sent her to the people of Mecca, and surrendered her as ransom for a number of Muslims who had been kept as prisoners at Mecca.
