Ibn Shihāb reported that Sahl ibn Sa‘d As-Sā‘idi (may Allah be pleased with him) said to him: "‘Uwaymir al-‘Ajlāni went to ‘Āsim ibn ‘Adiyy al-Ansāri and asked: ‘O ‘Āsim, tell me, if a man sees his wife (sleeping) with another man, should he kill him, whereupon you will kill him (in retribution), or what should he do? O ‘Āsim, ask the Messenger of Allah (may Allah’s peace and blessings be upon him) about that.' ‘Āsim asked the Messenger of Allah (may Allah’s peace and blessings be upon him) about that, but the Prophet disliked the question and considered it disgraceful, which upset ‘Āsim. When he returned to his family, ‘Uwaymir went to him and said: ‘O ‘Āsim, what did the Messenger of Allah (may Allah’s peace and blessings be upon him) say to you?’ ‘Āsim replied: ‘You did not bring me any good. The Messenger of Allah (may Allah’s peace and blessings be upon him) disliked the question which I asked him.’ Thereupon, ‘Uwaymir said: ‘By Allah! I will not stop until I ask him about that.’ So, he went to the Messenger of Allah (may Allah’s peace and blessings be upon him) while he was amongst people, and said: ‘O Messenger of Allah, if a man finds another man (sleeping) with his wife, should he kill him, whereupon you will kill him (in retribution), or what should he do?’ The Messenger of Allah (may Allah’s peace and blessings be upon him) said: ‘Something has been revealed concerning you and your wife. So, go and bring her.’” Sahl said: "They both engaged in Li‘ān and I witnessed it along with the people in the Prophet’s presence. When they were done, ‘Uwaymir said: ‘O Messenger of Allah, If I kept her as a wife, It would mean that I fabricated a lie against her then.’ So, he pronounced divorce against her three times before the Messenger of Allah (may Allah’s peace and blessings be upon him) ordered him to do so.'” Ibn Shihāb added: “So it became a tradition to dissolve the marriage of those spouses who are involved in a case of Li‘ān.”
