Sayyiduna Safwan bin Umayyah (may Allah be pleased with him) related: I was sleeping in the mosque on a cloak of mine worth thirty dirhams, and a man came to me and snatched it from me. The man was caught and brought to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) ordered that his hand be cut off. I came to him (peace and blessings be upon him) and said: Will you cut off his hand for the sake of thirty dirhams? It is his (I have given it to him). He (peace and blessings be upon him) said: "Why did you not do this before you brought him to me?"
