Uwaimir Al-ʿAjlani came to ʿAsim bin Adi Al-Ansari and asked, "O ʿAsim! Tell me, if a man sees his wife with another man, should he kill him, whereupon you would kill him in Qisas, or what should he do? O ʿAsim! Please ask Messenger of Allah ﷺ about that." ʿAsim asked Messenger of Allah ﷺ about that. Allah's Apostle disliked that question and considered it disgraceful. What ʿAsim heard from Messenger of Allah ﷺ was hard on him. When he returned to his family, 'Uwaimir came to him and said "O ʿAsim! What did Messenger of Allah ﷺ say to you?" ʿAsim said, "You never bring me any good. Messenger of Allah ﷺ disliked to hear the problem which I asked him about." 'Uwaimir said, "By Allah, I will not leave the matter till I ask him about it." So 'Uwaimir proceeded till he came to Messenger of Allah ﷺ who was in the midst of the people and said, "O Messenger of Allah ﷺ! If a man finds with his wife another man, should he kill him, whereupon you would kill him (in Qisas): or otherwise, what should he do?" Messenger of Allah ﷺ said, "Allah has revealed something concerning the question of you and your wife. Go and bring her here." So they both carried out the judgment of Lian, while I was present among the people (as a witness). When both of them had finished, 'Uwaimir said, "O Messenger of Allah ﷺ! If I should now keep my wife with me, then I have told a lie". Then he pronounced his decision to divorce her thrice before Allah's Apostle ordered him to do so. (Ibn Shihab said, "That was the tradition for all those who are involved in a case of Lian."
