A man came to Messenger of Allah ﷺ and said, "O Messenger of Allah ﷺ! Suppose a man saw another man with his wife, should he kill him whereupon you might kill him (i.e. the killer) (in Qisas) or what should he do?" So Allah revealed concerning their case what is mentioned of the order of Mula'ana. Allah's Apostle said to the man, "The matter between you and your wife has been decided." So they did Mula'ana in the presence of Messenger of Allah ﷺ and I was present there, and then the man divorced his wife. So it became a tradition to dissolve the marriage of those spouses who were involved in a case of Mula'ana. The woman was pregnant and the husband denied that he was the cause of her pregnancy, so the son was (later) ascribed to her. Then it became a tradition that such a son would be the heir of his mother, and she would inherit of him what Allah prescribed for her.  

أَنَّ رَجُلاً أَتَى رَسُولَ اللَّهِ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ رَجُلاً رَأَى مَعَ امْرَأَتِهِ رَجُلاً أَيَقْتُلُهُ فَتَقْتُلُونَهُ أَمْ كَيْفَ يَفْعَلُ فَأَنْزَلَ اللَّهُ فِيهِمَا مَا ذُكِرَ فِي الْقُرْآنِ مِنَ التَّلاَعُنِ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ قَدْ قُضِيَ فِيكَ وَفِي امْرَأَتِكَ قَالَ فَتَلاَعَنَا وَأَنَا شَاهِدٌ عِنْدَ رَسُولِ اللَّهِ ﷺ فَفَارَقَهَا فَكَانَتْ سُنَّةً أَنْ يُفَرَّقَ بَيْنَ الْمُتَلاَعِنَيْنِ وَكَانَتْ حَامِلاً فَأَنْكَرَ حَمْلَهَا وَكَانَ ابْنُهَا يُدْعَى إِلَيْهَا ثُمَّ جَرَتِ السُّنَّةُ فِي الْمِيرَاثِ أَنْ يَرِثَهَا وَتَرِثَ مِنْهُ مَا فَرَضَ اللَّهُ لَهَا  

[Machine] He said that a man from the Ansar came to the Messenger of Allah ﷺ and said, "O Messenger of Allah, what do you think about a man who finds another man with his wife, should he kill him?" So Allah revealed concerning this matter what was mentioned in the Quran about cursing. He said, "It has been decided concerning you and your wife." He said, "So we cursed each other, and I was a witness." Then they separated in the presence of the Messenger of Allah ﷺ . Afterwards, it was established in their case that they should be separated and that she was pregnant. He denied her pregnancy, so their son was called to his mother. Then the Sunnah was followed regarding inheritance, that the son inherits her and she inherits from him what is prescribed for her.  

أَنَّهُ قَالَ إِنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَرَأَيْتَ رَجُلًا وَجَدَ مَعَ امْرَأَتِهِ رَجُلًا أَيَقْتُلُهُ؟ فَأَنْزَلَ اللهُ ﷻ فِي شَأْنِهِ مَا ذُكِرَ فِي الْقُرْآنِ مِنَ التَّلَاعُنِ فَقَالَ «قَدْ قُضِيَ فِيكَ وَفِي امْرَأَتِكَ» قَالَ فَتَلَاعَنَا وَأَنَا شَاهِدٌ ثُمٌّ فَارَقَهَا عِنْدَ رَسُولِ اللهِ ﷺ فَكَانَتِ السُّنَّةُ بَعْدُ فِيهِمَا أَنْ يُفَرَّقَ بَيْنَ الْمُتَلَاعِنَيْنِ وَكَانَتْ حَامِلًا فَأَنْكَرَ حَمْلَهَا فَكَانَ ابْنُهَا يُدْعَى إِلَى أُمِّهِ ثُمَّ جَرَتِ السُّنَّةُ فِي الْمِيرَاثِ أَنَّهُ يَرِثُهَا ابْنُهَا وَتَرِثُ مِنْهُ مَا فُرِضَ لَهَا  

[Machine] A man came to the Messenger of Allah ﷺ and said, "O Messenger of Allah, what do you think about a man who sees his wife with another man; should he kill him and then be killed, or what should he do?" So Allah ﷻ revealed regarding them what is mentioned in the Qur'an about the cursing. The Messenger of Allah ﷺ said to him, "The matter has been decided regarding you and your wife." He said, "We cursed each other while I was present with the Messenger of Allah ﷺ." He said, "O Messenger of Allah, if I were to keep her, then I would have lied about her. So I separated from her and the practice (Sunnah) among them was that they would be separated between the two who cursed each other. And she was pregnant, so he denied her pregnancy. The practice after that regarding inheritance was that she could inherit from him what Allah had ordained for her."  

أَنَّ رَجُلًا أَتَى رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَرَأَيْتَ رَجُلًا رَأَى مَعَ امْرَأَتِهِ رَجُلًا أَيَقْتُلُهُ فَتَقْتُلُونَهُ بِهِ أَمْ كَيْفَ يَفْعَلُ بِهِ؟ فَأَنْزَلَ اللهُ ﷻ فِيهِمَا مَا ذُكِرَ فِي الْقُرْآنِ مِنَ التَّلَاعُنِ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «قَدْ قُضِيَ فِيكَ وَفِي امْرَأَتِكَ» قَالَ فَتَلَاعَنَا وَأَنَا شَاهِدٌ عِنْدَ رَسُولِ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ إِنْ أَمْسَكْتُهَا فَقَدْ كَذَبْتُ عَلَيْهَا فَفَارَقَهَا فَجَرَتِ السُّنَّةُ بَعْدُ فِيهِمَا أَنْ يُفَرَّقَ بَيْنَ الْمُتَلَاعِنَيْنِ وَكَانَتْ حَامِلًا فَأَنْكَرَ حَمْلَهَا وَكَانَ يُدْعَى إِلَيْهَا وَجَرَتِ السُّنَّةُ بَعْدُ فِي الْمِيرَاثِ أَنْ يَرِثَهَا فَتَرِثَ مِنْهُ مَا فَرَضَ اللهُ لَهَا
