A man came to Sayyiduna Imran bin Husayn (may Allah be pleased with him) and said: My slave has run away, and I have made a vow that if Allah returns him, I will cut off his hand. He said: Do not cut off his hand, "for the Messenger of Allah (peace and blessings be upon him) used to command giving charity and forbid mutilation."
