It is narrated from Muawiyah bin Suwaid, he says: I slapped one of my slaves, then when I came, my father was leading the Zuhr prayer, I prayed with him, when he finished the prayer, he held my hand and said to the slave: Take retribution from him, but he forgave me. Then he began to narrate this hadith: In the time of the Prophet, we were seven individuals from the descendants of Muqrin, and we had only one slave girl. One of us slapped her. When the Prophet Muhammad (peace and blessings be upon him) found out about this, he said: Set her free. We said: O Messenger of Allah, we have only this one slave girl. The Prophet (peace and blessings be upon him) said: Then let these people take service from her, but as soon as they become well-off, set her free.
