It is narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) that Sayyiduna ‘Uwaymir ‘Ajlani (may Allah be pleased with him) submitted:“O Messenger of Allah! If a person finds another man with his wife, what do you think he should do? Should he kill him? In that case, people (in retaliation) will also kill him, so what should he do?”The Messenger of Allah (peace and blessings be upon him) said:“Allah Almighty has revealed guidance regarding you and your wife. Go and bring your wife with you.”Sayyiduna Sahl (may Allah be pleased with him) said: Then both husband and wife performed li‘an (mutual cursing). I was also present with the people at the time with the Messenger of Allah (peace and blessings be upon him). When both of them finished the li‘an, Sayyiduna ‘Uwaymir (may Allah be pleased with him) submitted:“O Messenger of Allah! If after this I keep her with me, it would mean that I am a liar.”Then, before the Noble Prophet (peace and blessings be upon him) could say anything, he pronounced three divorces upon her. Ibn Shihab Zuhri (may Allah have mercy on him) said: Then this became the established procedure for those who perform li‘an.
