It is narrated from Bilal bin Yasaf (may Allah have mercy on him) that we were selling cloth in the house of Sayyiduna Suwaid bin Muqarrin (may Allah be pleased with him) when a slave girl came out and said something to a man, so the man slapped her. Upon this, Sayyiduna Suwaid bin Muqarrin (may Allah be pleased with him) said to him: "Did you slap her on the face? Indeed, I was the seventh among seven (brothers), and we had only one servant girl. When one of us slapped her, the Prophet (peace and blessings of Allah be upon him) ordered him to set her free."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that I heard the Noble Prophet (peace and blessings be upon him) say: "Whoever slaps his slave or beats him without fault, then its expiation is that he should set him free."

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."

It is narrated from Sayyiduna Suwaid bin Muqarrin Al-Muzani (may Allah be pleased with him) that he saw a person who had slapped his slave, so he said: Do you not know that it is forbidden to strike the face? I saw during the time of the Messenger of Allah (peace and blessings be upon him) that we were seven brothers and had only one maidservant. If any one of us slapped her, the Prophet (peace and blessings be upon him) ordered us to set her free.

Zadhan Abu Umar narrates that we were with Sayyiduna Ibn Umar (may Allah be pleased with them), so he called one of his slaves whom he had beaten. He removed the cloth from his back and asked, "Do you feel pain?" He replied, "No." So he set him free. Then he picked up a stick from the ground and said, "There is not even as much reward in this for me as the weight of this stick." I asked, "Abu Abdur Rahman! Why do you say this?" He said, "I heard the Prophet (peace and blessings of Allah be upon him) say: 'Whoever beats his slave without fault or slaps him, the expiation for that is to set him free.'"
