Ibn Hazm related that a thief was brought to Abu Bakr r.a. who said, “Cut off his hand.” The thief said, “Forgive me, O Khalifah of the Messenger of Allah, for I have never stolen prior to this.” Abu Bakr r.a said, “You have lied, for by the One Who has my soul in His Hand, Allah does not suddenly take a believer on the first time that he sins”
Anas bin Malik r,a, related that a thief was brought before ‘Umar ibn Khattab r.a. The thief said, “By Allah, I have never stolen before this.” Umar said, “You have lied, by the Lord of Umar. Allah does not take a slave at the first sin.” It is said that ‘Ali ibn Abi Talib said, “O Leader of the Believers, Allah is more forbearing than to take a slave for his first sin.” Umar then gave the order and the man’s hand was cut off. Then ‘Ali asked him to speak the truth – how many times before had he stolen? He said, “21 times.”
