الأخلاق الذميمة
Ibn ‘Umar (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever beats his slave boy or slaps him for something that he has not done, then the expiation for that is to set him free."  
عن ابن عمر -رضي الله عنهما- أن النبي -صلى الله عليه وسلم- قال: «من ضرب غلاما له حدا لم يأته، أو لَطَمَه، فإن كفارته أن يعتقه».

شرح الحديث :


Whoever hits his slave boy while the boy did not do what deserves punishment, then the expiation for this sin is to manumit the slave boy.
