Musannaf Ibn Abi Shaybah 30060 — A man who confesses to theft: how

Subay' Abu Salim said: I was present with Sayyiduna Hasan bin Ali (may Allah be pleased with him) when a man who had confessed to theft was brought. At this Sayyiduna Hasan said: Perhaps you snatched it, so that he would say: No. This continued until the man had confessed before him two or three times; then on his order his hand was cut off.
