"We were with the Prophet said to him: 'By the One in Whose hand is my soul, I will pass judgment between you according to the Book of Allah, the Mighty and Sublime. As for the one hundred sheep and the servant, take them back, and your son is to be given one hundred lashes and exiled for a year. O Unais, go tomorrow to the wife of this man and if she confesses, then stone her to death.' She did confess, so he stoned her to death."
Sunan an-Nasa'i Book 49, Hadith 33
