Musannaf Ibn Abi Shayba 13:2929

Abu Bakr narrated to us, he said: Ibn Mahdi narrated to us, from Hammad ibn Salamah, from Qatadah and Humayd, from al-Hasan, that a man from Quraysh stole a camel, so the Prophet, peace and blessings of Allah be upon him, cut off his hand. He said: And his testimony was considered valid.
