Hadith
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنِ ابْنِ شِهَابٍ، أَنَّ سَهْلَ بْنَ سَعْدٍ السَّاعِدِيَّ، أَخْبَرَهُ أَنَّ عُوَيْمِرًا الْعَجْلاَنِيَّ جَاءَ إِلَى عَاصِمِ بْنِ عَدِيٍّ الأَنْصَارِيِّ، فَقَالَ لَهُ يَا عَاصِمُ أَرَأَيْتَ رَجُلاً وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً، أَيَقْتُلُهُ فَتَقْتُلُونَهُ، أَمْ كَيْفَ يَفْعَلُ سَلْ لِي يَا عَاصِمُ عَنْ ذَلِكَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَسَأَلَ عَاصِمٌ عَنْ ذَلِكَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَكَرِهَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْمَسَائِلَ وَعَابَهَا حَتَّى كَبُرَ عَلَى عَاصِمٍ مَا سَمِعَ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلَمَّا رَجَعَ عَاصِمٌ إِلَى أَهْلِهِ جَاءَ عُوَيْمِرٌ فَقَالَ يَا عَاصِمُ مَاذَا قَالَ لَكَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ عَاصِمٌ لَمْ تَأْتِنِي بِخَيْرٍ، قَدْ كَرِهَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْمَسْأَلَةَ الَّتِي سَأَلْتُهُ عَنْهَا. قَالَ عُوَيْمِرٌ وَاللَّهِ لاَ أَنْتَهِي حَتَّى أَسْأَلَهُ عَنْهَا فَأَقْبَلَ عُوَيْمِرٌ حَتَّى أَتَى رَسُولَ اللَّهِ صلى الله عليه وسلم وَسَطَ النَّاسِ فَقَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ رَجُلاً وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً، أَيَقْتُلُهُ فَتَقْتُلُونَهُ، أَمْ كَيْفَ يَفْعَلُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " قَدْ أَنْزَلَ اللَّهُ فِيكَ وَفِي صَاحِبَتِكَ فَاذْهَبْ فَأْتِ بِهَا ". قَالَ سَهْلٌ فَتَلاَعَنَا وَأَنَا مَعَ النَّاسِ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلَمَّا فَرَغَا قَالَ عُوَيْمِرٌ كَذَبْتُ عَلَيْهَا يَا رَسُولَ اللَّهِ، إِنْ أَمْسَكْتُهَا، فَطَلَّقَهَا ثَلاَثًا قَبْلَ أَنْ يَأْمُرَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم. قَالَ ابْنُ شِهَابٍ فَكَانَتْ تِلْكَ سُنَّةُ الْمُتَلاَعِنَيْنِ.
Narrated Sahl bin Sa`d As-Sa`idi:Uwaimir Al-`Ajlani came to `Asim bin Adi Al-Ansari and asked, "O `Asim! 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 `Asim! Please ask Allah's Messenger (ﷺ) about that." `Asim asked Allah's Messenger (ﷺ) about that. Allah's Apostle disliked that question and considered it disgraceful. What `Asim heard from Allah's Messenger (ﷺ) was hard on him. When he returned to his family, 'Uwaimir came to him and said "O `Asim! What did Allah's Messenger (ﷺ) say to you?" `Asim said, "You never bring me any good. Allah's Messenger (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 Allah's Messenger (ﷺ) who was in the midst of the people and said, "O Allah's Messenger (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?" Allah's Messenger (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 Allah's Messenger (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)
