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."  

لَهُ يَا عَاصِمُ أَرَأَيْتَ رَجُلاً وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً أَيَقْتُلُهُ فَتَقْتُلُونَهُ أَمْ كَيْفَ يَفْعَلُ سَلْ لِي يَا عَاصِمُ عَنْ ذَلِكَ رَسُولَ اللَّهِ ﷺ فَسَأَلَ عَاصِمٌ عَنْ ذَلِكَ رَسُولَ اللَّهِ ﷺ فَكَرِهَ رَسُولُ اللَّهِ ﷺ الْمَسَائِلَ وَعَابَهَا حَتَّى كَبُرَ عَلَى عَاصِمٍ مَا سَمِعَ مِنْ رَسُولِ اللَّهِ ﷺ فَلَمَّا رَجَعَ عَاصِمٌ إِلَى أَهْلِهِ جَاءَ عُوَيْمِرٌ فَقَالَ يَا عَاصِمُ مَاذَا قَالَ لَكَ رَسُولُ اللَّهِ ﷺ فَقَالَ عَاصِمٌ لَمْ تَأْتِنِي بِخَيْرٍ قَدْ كَرِهَ رَسُولُ اللَّهِ ﷺ الْمَسْأَلَةَ الَّتِي سَأَلْتُهُ عَنْهَا قَالَ عُوَيْمِرٌ وَاللَّهِ لاَ أَنْتَهِي حَتَّى أَسْأَلَهُ عَنْهَا فَأَقْبَلَ عُوَيْمِرٌ حَتَّى أَتَى رَسُولَ اللَّهِ ﷺ وَسَطَ النَّاسِ فَقَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ رَجُلاً وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً أَيَقْتُلُهُ فَتَقْتُلُونَهُ أَمْ كَيْفَ يَفْعَلُ فَقَالَ رَسُولُ اللَّهِ ﷺ قَدْ أَنْزَلَ اللَّهُ فِيكَ وَفِي صَاحِبَتِكَ فَاذْهَبْ فَأْتِ بِهَا قَالَ سَهْلٌ فَتَلاَعَنَا وَأَنَا مَعَ النَّاسِ عِنْدَ رَسُولِ اللَّهِ ﷺ فَلَمَّا فَرَغَا قَالَ عُوَيْمِرٌ كَذَبْتُ عَلَيْهَا يَا رَسُولَ اللَّهِ إِنْ أَمْسَكْتُهَا فَطَلَّقَهَا ثَلاَثًا قَبْلَ أَنْ يَأْمُرَهُ رَسُولُ اللَّهِ ﷺ قَالَ ابْنُ شِهَابٍ فَكَانَتْ تِلْكَ سُنَّةُ الْمُتَلاَعِنَيْنِ  

The wife of Rifaʿa Al-Qurazi came to Messenger of Allah ﷺ and said, "O Messenger of Allah ﷺ! Rifaʿa divorced me irrevocably. After him I married ʿAbdur-Rahman bin Az-Zubair Al-Qurazi who proved to be impotent." Messenger of Allah ﷺ said to her, "Perhaps you want to return to Rifaʿa? Nay (you cannot return to Rifaʿa) until you and ʿAbdur-Rahman consummate your marriage."  

أَنَّ امْرَأَةَ رِفَاعَةَ الْقُرَظِيِّ جَاءَتْ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ رِفَاعَةَ طَلَّقَنِي فَبَتَّ طَلاَقِي وَإِنِّي نَكَحْتُ بَعْدَهُ عَبْدَ الرَّحْمَنِ بْنَ الزَّبِيرِ الْقُرَظِيَّ وَإِنَّمَا مَعَهُ مِثْلُ الْهُدْبَةِ قَالَ رَسُولُ اللَّهِ ﷺ لَعَلَّكِ تُرِيدِينَ أَنْ تَرْجِعِي إِلَى رِفَاعَةَ لاَ حَتَّى يَذُوقَ عُسَيْلَتَكِ وَتَذُوقِي عُسَيْلَتَهُ  

A man divorced his wife thrice (by expressing his decision to divorce her thrice), then she married another man who also divorced her. The Prophet ﷺ was asked if she could legally marry the first husband (or not). The Prophet ﷺ replied, "No, she cannot marry the first husband unless the second husband consummates his marriage with her, just as the first husband had done."  

أَنَّ رَجُلاً طَلَّقَ امْرَأَتَهُ ثَلاَثًا فَتَزَوَّجَتْ فَطَلَّقَ فَسُئِلَ النَّبِيُّ ﷺ أَتَحِلُّ لِلأَوَّلِ قَالَ لاَ حَتَّى يَذُوقَ عُسَيْلَتَهَا كَمَا ذَاقَ الأَوَّلُ
