Sahih al-Bukhari 6633, 6634

Ismail narrated to us; he said: Malik narrated to me, from Ibn Shihab, from Ubaydullah ibn Abdullah ibn Utbah ibn Mas'ud, from Abu Hurayrah and Zayd ibn Khalid, who informed him that two men brought a dispute to the Messenger of Allah, peace and blessings be upon him. One said, ‘Judge between us by the Book of Allah.’ The other, who was more learned, said, ‘Yes, Messenger of Allah, judge between us by the Book of Allah, and allow me to speak.’ He said, ‘Speak.’ The man said that his son was a hired worker for the other man—Malik explained that an asif is a hired worker—and had committed adultery with his wife. He was told that stoning was due for his son, so he ransomed him with one hundred sheep and a female slave of his. Then he asked the people of knowledge, who told him his son was liable to one hundred lashes and exile for a year, while stoning was due for the man's wife. The Messenger of Allah, peace and blessings be upon him, said: ‘By the One in whose hand is my soul, I will certainly judge between you by the Book of Allah. Your sheep and your female slave are to be returned to you.’ He gave the son one hundred lashes and exiled him for a year. He ordered Unays al-Aslami to go to the other man's wife and, if she confessed, to stone her. She confessed, and he stoned her.
