I witnessed the case of Lian (the case of a man who charged his wife for committing illegal sexual intercourse when I was fifteen years old. The Prophet ﷺ ordered that they be divorced, and the husband said, "If I kept her, I would be a liar." I remember that Az-Zubair also said, "(It was said) that if that woman brought forth the child with such-and-such description, her husband would prove truthful, but if she brought it with such-and-such description looking like a Wahra (a red insect), he would prove untruthful." I heard Az-Zubair also saying, "Finally she gave birth to a child of description which her husband disliked .  

شَهِدْتُ الْمُتَلاَعِنَيْنِ وَأَنَا ابْنُ خَمْسَ عَشْرَةَ فَرَّقَ بَيْنَهُمَا فَقَالَ زَوْجُهَا كَذَبْتُ عَلَيْهَا إِنْ أَمْسَكْتُهَا  

Ibn ʿAbbas mentioned the couple who had taken the oath of Lian. ʿAbdullah bin Shaddad said (to him), "Was this woman about whom Messenger of Allah ﷺ said, 'If I were ever to stone to death any woman without witnesses. (I would have stoned that woman to death)?' Ibn ʿAbbas replied," No, that lady exposed herself (by her suspicious behavior).  

قَالَ رَسُولُ اللَّهِ ﷺ لَوْ كُنْتُ رَاجِمًا امْرَأَةً عَنْ غَيْرِ بَيِّنَةٍ قَالَ لاَ تِلْكَ امْرَأَةٌ أَعْلَنَتْ  

Lian was mentioned in the presence of the Prophet, ʿAsim bin Adi said a statement about it, and when he left, a man from his tribe came to him complaining that he had seen a man with his wife. ʿAsim said, "I have been put to trial only because of my statement." So he took the man to the Prophet ﷺ and the man told him about the incident. The man (husband) was of yellow complexion, thin, and of lank hair, while the man whom he had accused of having been with his wife, was reddish brown with fat thick legs and fat body. The Prophet ﷺ said, "O Allah! Reveal the truth." Later on the lady delivered a child resembling the man whom the husband had accused of having been with her. So the Prophet ﷺ made them take the oath of Lian. A man said to Ibn ʿAbbas in the gathering, "Was that the same lady about whom the Prophet ﷺ said, "If I were to stone any lady (for committing illegal sexual intercourse) to death without witnesses, I would have stoned that lade to death?" Ibn ʿAbbas said, "No, that was another lady who used to behave in such a suspicious way among the Muslims that one might accuse her of committing illegal sexual intercourse."  

التَّلاَعُنُ عِنْدَ النَّبِيِّ ﷺ فَقَالَ عَاصِمُ بْنُ عَدِيٍّ فِي ذَلِكَ قَوْلاً ثُمَّ انْصَرَفَ وَأَتَاهُ رَجُلٌ مِنْ قَوْمِهِ يَشْكُو أَنَّهُ وَجَدَ مَعَ أَهْلِهِ فَقَالَ عَاصِمٌ مَا ابْتُلِيتُ بِهَذَا إِلاَّ لِقَوْلِي فَذَهَبَ بِهِ إِلَى النَّبِيِّ ﷺ فَأَخْبَرَهُ بِالَّذِي وَجَدَ عَلَيْهِ امْرَأَتَهُ وَكَانَ ذَلِكَ الرَّجُلُ مُصْفَرًّا قَلِيلَ اللَّحْمِ سَبِطَ الشَّعَرِ وَكَانَ الَّذِي ادَّعَى عَلَيْهِ أَنَّهُ وَجَدَهُ عِنْدَ أَهْلِهِ آدَمَ خَدْلاً كَثِيرَ اللَّحْمِ فَقَالَ النَّبِيُّ ﷺ اللَّهُمَّ بَيِّنْ فَوَضَعَتْ شَبِيهًا بِالرَّجُلِ الَّذِي ذَكَرَ زَوْجُهَا أَنَّهُ وَجَدَهُ عِنْدَهَا فَلاَعَنَ النَّبِيُّ ﷺ بَيْنَهُمَا فَقَالَ رَجُلٌ لاِبْنِ عَبَّاسٍ فِي الْمَجْلِسِ هِيَ الَّتِي قَالَ النَّبِيُّ ﷺ لَوْ رَجَمْتُ أَحَدًا بِغَيْرِ بَيِّنَةٍ رَجَمْتُ هَذِهِ فَقَالَ لاَ تِلْكَ امْرَأَةٌ كَانَتْ تُظْهِرُ فِي الإِسْلاَمِ السُّوءَ
