Ibn Shihab informed me of Lian and the tradition related to it, referring to the narration of Sahl bin Saʿd, the brother of Bani Saʿidi He said, "An Ansari man came to Messenger of Allah ﷺ and said, 'O Allah's Apostle! If a man saw another man with his wife, should he kill him, or what should he do?' So Allah revealed concerning his affair what is mentioned in the Holy Qur'an about the affair of those involved in a case of Lian. The Prophet ﷺ said, 'Allah has given His verdict regarding you and your wife.' So they carried out Lian in the mosque while I was present there. When they had finished, the man said, "O Messenger of Allah ﷺ! If I should now keep her with me as a wife then I have told a lie about her. Then he divorced her thrice before Messenger of Allah ﷺ ordered him, when they had finished the Lian process. So he divorced her in front of the Prophet ﷺ ." Ibn Shihab added, "After their case, it became a tradition that a couple involved in a case of Lian should be separated by divorce. That lady was pregnant then, and later on her son was called by his mother's name. The tradition concerning their inheritance was that she would be his heir and he would inherit of her property the share Allah had prescribed for him." Ibn Shihab said that Sahl bin Saʿd As'Saidi said that the Prophet ﷺ said (in the above narration), "If that lady delivers a small red child like a lizard, then the lady has spoken the truth and the man was a liar, but if she delivers a child with black eyes and huge lips, then her husband has spoken the truth." Then she delivered it in the shape one would dislike (as it proved her guilty). (Using translation from Bukhārī 5309)   

أَنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَرَأَيْتَ رَجُلًا وَجَدَ مَعَ امْرَأَتِهِ رَجُلًا أَيَقْتُلُهُ أَمْ كَيْفَ يَفْعَلُ؟ فَأَنْزَلَ اللهُ فِي شَأْنِهِ مَا ذُكِرَ فِي الْقُرْآنِ مِنْ أَمْرِ الْمُتَلَاعِنَيْنِ فَقَالَ النَّبِيُّ ﷺ قَدْ قَضَى اللهُ فِيكَ وَفِي امْرَأَتِكَ قَالَ فَتَلَاعَنَا فِي الْمَسْجِدِ وَأَنَا شَاهِدٌ فَلَمَّا فَرَغَا قَالَ كَذَبْتُ عَلَيْهَا يَا رَسُولَ اللهِ إِنْ أَمْسَكْتُهَا فَطَلَّقَهَا ثَلَاثًا قَبْلَ أَنْ يَأْمُرَهُ رَسُولُ اللهِ ﷺ حِينَ فَرَغَا مِنَ التَّلَاعُنِ فَفَارَقَهَا عِنْدَ النَّبِيِّ ﷺ وَقَالَ ذَاكَ تَفْرِيقٌ بَيْنَ كُلِّ مُتَلَاعِنَيْنِ قَالَ ابْنُ جُرَيْجٍ قَالَ ابْنُ شِهَابٍ كَانَتِ السُّنَّةُ بَعْدَهُمَا أَنْ يُفَرَّقَ بَيْنَ الْمُتَلَاعِنَيْنِ وَكَانَتْ حَامِلًا وَكَانَ ابْنُهَا يُدْعَى لِأُمِّهِ ثُمَّ جَرَتِ السُّنَّةُ فِي مِيرَاثِهَا أَنَّهَا تَرِثُهُ وَيَرِثُ مِنْهَا مَا فَرَضَ اللهُ ﷻ لَهُمَا قَالَ ابْنُ جُرَيْجٍ عَنِ ابْنِ شِهَابٍ عَنْ سَهْلِ بْنِ سَعْدٍ فِي هَذَا الْحَدِيثِ أَنَّ النَّبِيَّ ﷺ قَالَ إِنْ جَاءَتْ بِهِ أَحْمَرَ قَصِيرًا أَوْحَرَ فَمَا أَرَاهَا إِلَّا قَدْ صَدَقَتْ وَكَذَبَ عَلَيْهَا وَإِنْ جَاءَتْ بِهِ أَسْوَدَ أَعْيَنَ ذَا أَلْيَتَيْنِ فَلَا أَرَاهُ إِلَّا قَدْ صَدَقَ عَلَيْهَا فَجَاءَتْ بِهِ عَلَى الْمَكْرُوهِ مِنْ ذَلِكَ  

[Machine] A man came to the Messenger of Allah ﷺ and said, "O Messenger of Allah, what do you think if a man finds another man with his wife, should he kill him and you kill her?" So Allah revealed concerning both of them what is mentioned in the Quran regarding the adulterous couple. The Messenger of Allah ﷺ said, "Allah has decided in your case and in the case of your wife." He said, "We curse each other and I am a witness before the Messenger of Allah ﷺ." The Prophet ﷺ said, "If you keep her, you have lied about her, so divorce her." The tradition among them was to separate between the two cursed individuals, and she was pregnant and denied her pregnancy. The Messenger of Allah ﷺ then said, "Her child will be called to her." Then the tradition regarding inheritance was implemented, that he would inherit her and she would inherit from him what Allah had ordained for her. Abu Ya'la said, "The matter was decided regarding him." He said, "He and al-Hasan." He said, "O Messenger of Allah, if I keep her and they testify, it will be a tradition between them and their speech will be about other than that."  

أَنَّ رَجُلًا أَتَى رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَرَأَيْتَ رَجُلًا وَجَدَ مَعَ امْرَأَتِهِ رَجُلًا أَيَقْتُلُهُ فَتَقْتُلُونَهُ أَمْ كَيْفَ يَفْعَلُ؟ فَأَنْزَلَ اللهُ ﷻ فِيهِمَا مَا ذُكِرَ فِي الْقُرْآنِ فِي الْمُتَلَاعِنَيْنِ فَقَالَ رَسُولُ اللهِ ﷺ قَدْ قَضَى اللهُ فِيكَ وَفِي امْرَأَتِكَ قَالَ فَتَلَاعَنَا وَأَنَا شَاهِدٌ عِنْدَ رَسُولِ اللهِ ﷺ فَقَالَ إِنْ أَمْسَكْتُهَا فَقَدْ كَذَبْتُ عَلَيْهَا فَفَارَقَهَا وَكَانَتِ السُّنَّةُ فِيهِمَا أَنْ يُفَرِّقَا بَيْنَ الْمُتَلَاعِنَيْنِ وَكَانَتْ حَامِلًا فَأَنْكَرَ حَمْلَهَا وَكَانَ ابْنُهَا يُدْعَى إِلَيْهَا ثُمَّ جَرَتِ السُّنَّةُ فِي الْمِيرَاثِ أَنْ يَرِثَهَا وَتَرِثُ مِنْهُ مَا فَرَضَ اللهُ لَهَا قَالَ أَبُو يَعْلَى قَدْ قُضِيَ فِيكَ قَالَ هُوَ وَالْحَسَنُ فَقَالَ يَا رَسُولَ اللهِ إِنْ أَمْسَكْتُهَا وَقَالَا فَكَانَتْ سُنَّةً بَيْنَهُمْ وَحَدِيثُهُمْ فِيمَا سِوَى ذَلِكَ وَاحِدٌ  

[Machine] "A Bedouin man from the tribe of Banu Fazara came to the Prophet ﷺ and said, 'Indeed, my wife has given birth to a dark-skinned boy.' The Prophet ﷺ said to him, 'Do you have any camels?' He replied, 'Yes.' The Prophet ﷺ asked, 'What are their colors?' He answered, 'Red.' The Prophet ﷺ then asked, 'Do any of them have white markings?' He replied, 'Yes, some of them have white markings.' The Prophet ﷺ said, 'Perhaps it is from the genes of one of them that the child inherited this.' The phrase 'perhaps it is from the genes of one of them' is a narration from Imam Shafi'i, and in the narration of Qutaiba, it mentions that a man from the tribe of Banu Fazara came to the Prophet ﷺ and said, 'Perhaps it is from the genes of one of them.'"  

أَنَّ أَعْرَابِيًّا مِنْ بَنِي فَزَارَةَ أَتَى النَّبِيَّ ﷺ فَقَالَ إِنَّ امْرَأَتِي وَلَدَتْ غُلَامًا أَسْوَدَ فَقَالَ لَهُ النَّبِيُّ ﷺ هَلْ لَكَ مِنْ إِبِلٍ؟ قَالَ نَعَمْ قَالَ فَمَا أَلْوَانُهَا؟ قَالَ حُمْرٌ قَالَ هَلْ فِيهَا مِنْ أَوْرَقَ؟ قَالَ إِنَّ فِيهَا لَوُرْقًا قَالَ فَأَنَّى أَصَابَهَا ذَلِكَ؟ قَالَ لَعَلَّهُ عِرْقٌ نَزَعَهُ فَقَالَ النَّبِيُّ ﷺ وَهَذَا لَعَلَّهُ نَزَعَهُ عِرْقٌ لَفْظُ حَدِيثِ الشَّافِعِيِّ وَفِي رِوَايَةِ قُتَيْبَةَ جَاءَ رَجُلٌ مِنْ بَنِي فَزَارَةَ إِلَى النَّبِيِّ ﷺ وَقَالَ عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ
