"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."
