It is narrated from Humaid At-Tawil that he heard Qatadah (may Allah have mercy on him) asking Anas bin Malik (may Allah be pleased with him) about cutting off the hand. So Anas (may Allah be pleased with him) said: "I went to Abu Bakr As-Siddiq (may Allah be pleased with him), and he cut off the hand of a thief for something which I would not like to take even for three dirhams."
