Hadith.5105 - Al-Alaa narrated from Muhammad ibn Muslim from Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) who said: I asked Imam (as) about a child who steals. Imam (as) said: "If he is seven years old or younger, the punishment is lifted from him. But if he repeats the act after the age of seven, his fingertip is to be cut off or scraped until it bleeds. If he repeats it again, a part below his fingertip is to be cut off. If he steals again after that and has reached nine years of age, his hand is to be cut off. None of the prescribed punishments of Allah (swt), the Mighty and Majestic, are to be neglected."

Hadith.5106 - A man came to Commander of the Faithful (as) and confessed to theft. Commander of the Faithful (as) asked him: "Do you recite anything from the Book of Allah (swt), the Mighty and Majestic?" The man replied: "Yes, Surah Al-Baqarah." Imam (as) said: "I have pardoned your hand for the sake of Surah Al-Baqarah." Al-Ashath objected, saying: "Are you suspending one of the punishments prescribed by Allah (swt), the Exalted?" Commander of the Faithful (as) replied: "And what do you know about this matter? When evidence is established, the Imam has no authority to pardon, but when a man confesses against himself, then it is up to the Imam - if he wishes, he may pardon, and if he wishes, he may order the cutting."
