An-Nisa · 4:16

16. If two of your men commit a sexual offence – whether they are married or unmarried – punish them with words and blows, humiliating and disciplining them. If they turn away from what they were doing and correct themselves, then do not harm them. Those who turn away from a sin and ask for forgiveness are like those who have not sinned. Allah turns to those who repent to Him asking for forgiveness, and is Compassionate with them. The ruling of this verse was replaced with the ruling that unmarried men who have illicit sexual relations should be whipped a hundred times and banished for a year, and married men who have illicit sexual relations should be stoned.
