Sahih al-Bukhari 6835, 6836

Narrated Abu Huraira and Zaid bin Khalid:A bedouin came to the Prophet (ﷺ) while he (the Prophet) was sitting, and said, "O Allah's Messenger (ﷺ)! Give your verdict according to Allah's Laws (in our case)." Then his opponent got up and said, "He has told the truth, O Allah's Messenger (ﷺ)! Decide his case according to Allah's Laws. My son was a laborer working for this person, and he committed illegal sexual intercourse with his wife, and the people told me that my son should be stoned to death, but I offered one-hundred sheep and a slave girl as a ransom for him. Then I asked the religious learned people, and they told me that my son should be flogged with one-hundred stripes and be exiled for one year." The Prophet (ﷺ) said, "By Him in Whose Hand my soul is, I will judge you according to Allah's Laws. The sheep and the slave girl will be returned to you and your son will be flogged one-hundred stripes and be exiled for one year. And you, O Unais! Go to the wife of this man (and if she confesses), stone her to death." So Unais went in the morning and stoned her to death (after she had confessed).
