It is narrated from Muawiyah bin Suwaid bin Muqrin (may Allah have mercy on him) that I slapped one of my slaves, so he ran away. My father called me and said, "Retribution will be taken from you." We were seven sons of Muqrin and had only one maidservant. One of our brothers slapped her, and this was mentioned before the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) said: "Order them to set her free." It was submitted to the Prophet (peace and blessings of Allah be upon him) that they have no other servant besides her. The Prophet (peace and blessings of Allah be upon him) said: "Let her serve them, and when they no longer need her, set her free."
