Narrated 'Ali: That the Messenger of Allah (ﷺ) said: The pen has been lifted from three; for the sleeping person until he awakens, for the boy until he becomes a young man and for the mentally insane until he regains sanity.

Narrated 'Aishah: that the Messenger of Allah (ﷺ): Avert the legal penalties from the Muslims as much as possible, if he has a way out then leave him to his way, for if the Imam makes a mistake in forgiving it would be better than making mistake in punishment.

Narrated Abu Hurairah: That the Messenger of Allah (ﷺ) said: Whoever relieves a Muslim of a burden from the burdens of the world, Allah will relieve him of a burden from the burdens of the Hereafter. And whoever covers (the faults of) a Muslim, Allah will cover (his faults) for him in the world and the Hereafter. And Allah is engaged in helping the worshipper as long as the worshipper is engaged in helping his brother.

Narrated Ibn 'Umar: That the Messenger of Allah (ﷺ) said: The Muslim is the brother of the Muslim, he doesn't oppress him and doesn't put him into ruin, and whoever is concerned for the needs of his brother, Allah is concerned for his needs, and whoever relieves a Muslim of a burden, Allah will relieve him of a burden from the burdens of the Day of Judgement and whoever covers (the faults of) a Muslim, Allah will cover (his faults) on the Day of Judgement.

Narrated Ibn 'Abbas: That the Prophet (ﷺ) said to Ma'iz bin Malik: Is what has reached me about you true? He said: What has reached you about me? He said: It has reached me that you had relations with the slave-maid of the family of so-and-so He said: Yes. So he testified four times, and he gave the order that he be stoned.

Narrated Abu Hurairah: Ma'iz Al-Aslamu came to the Messenger of Allah (ﷺ) and said that he had committed adultery, so he (ﷺ) turned away from him. Then he approached from his other side and said: '[O Messenger of Allah!] I have committed adultery.' So he turned away from him. The he came from his other side and said: 'O Messenger of Allah! I have committed adultery.' So he gave the order (for stoning) upon the fourth time. He was taken to Al-Harrah and stoned with rocks, he ran swiftly until he passed a man with a camel whip who beat him with it, and the people beat him until he died. They mentioned to the Messenger of Allah (ﷺ), that he ran upon feeling the rocks at the time of death. So the Messenger of Allah (ﷺ) said: 'Why didn't you leave him?'

Narrated Jabir bin 'Abdullah: A man from the tribe of Aslam came to the Prophet (ﷺ) and confessed adultery. He turned away from him, the he confessed (again). Then he turned away from him (again) until he had testified against himself four times. So the Prophet (ﷺ) said: Are you insane? He said: No He said: Are you married? He said: Yes . So he gave the order and he was stoned at the Musalla. He ran when he was stuck by the stones, and he was caught and stoned until he died. So the Messenger of Allah (ﷺ) spoke well of him but he did not perform the (funeral) Salat for him.

Narrated 'Aishah: The Quraish were troubled by the affair of a woman from the tribe of Makhzum who stole. So they said: 'Who will speak about her to the Messenger of Allah (ﷺ)?' They said: 'Who can do it other than Usamah bin Zaid, the one dear to the Messenger of Allah?' So Usamah spoke with him, the Messenger of Allah (ﷺ) said: 'Do you intercede about a penalty from Allah's penalties?' Then he stood up and adressed the people saying: 'Those before you were only destroyed because they used to leave a noble person if he stole. And if a weak person stole they would establish the penalty upon him. And by Allah! If Fatimah bint Muhammad stole, then I would cut off her hand.

Umar bin Al-Khattab said: The Messenger of Allah (ﷺ) stoned, Abu Bakr stoned, and I stoned. If I didn't dislike that I add to the Book of Allah. I would have written it in the Mushaf, for I fear that there will come a people and they will not find it in the Book of Allah, so they will disbelieve in it.

Umar bin Al-Khattab said: Verily Allah sent Muhammad (ﷺ) with the truth, and he revealed the Book to him. Among what was revealed to him was the Ayah of stoning. So the Messenger of Allah (ﷺ) stoned, and we stoned after him. I fear that time will pass over the people such that someone will say 'We do not see stoning in the Book of Allah.' They will be misguided by leaving an obligation which Allah revealed. Indeed stoning is the retribution for the adulterer if he was married and the evidence has been established, or due to pregnancy, or confession.
