(93) بَابُ مَنْ لَطَمَ عَبْدَهُ فَلْيُعْتِقْهُ مِنْ غَيْرِ إِيجَابٍ
Mu'awiya ibn Muqarrin said, "I slapped a mawla of mine and he fled.Then my father called me and said, 'I will tell you a story. We, the sonsof Muqarrin, were seven, and we had one servant. Then one of us slappedher and that was mentioned to the Messenger of Allah, may Allah bless himand grant him peace. He said, 'Order them to set her free.' The Prophet,may Allah bless him and grant him peace, was told. 'She is the only servantthey have.' He said, 'Then let them hire her and when they no longer needher, let her go on her way.'"
