I asked Ibn ʿUmar about those who were involved in a case of Lien. He said, "The Prophet ﷺ said to those who were involved in a case of Lien, 'Your accounts are with Allah. One of you two is a liar, and you (the husband) have no right over her (she is divorced)." The man said, 'What about my property (Mahr) ?' The Prophet ﷺ said, 'You have no right to get back your property. If you have told the truth about her then your property was for the consummation of your marriage with her; and if you told a lie about her, then you are less rightful to get your property back.' " Sufyan, a sub-narrator said: I learned the Hadith from ʿAmr. Narrated Aiyub: I heard Saʿid bin Jubair saying, "I asked Ibn ʿUmar, 'If a man (accuses his wife for an illegal sexual intercourse and) carries out the process of Lian (what will happen)?' Ibn ʿUmar set two of his fingers apart. (Sufyan set his index finger and middle finger apart.) Ibn ʿUmar said, 'The Prophet ﷺ separated the couple of Bani Al-Ajlan by divorce and said thrice, "Allah knows that one of you two is a liar; so will one of you repent (to Allah)?' "  

سَأَلْتُ ابْنَ عُمَرَ عَنِ الْمُتَلاَعِنَيْنِ فَقَالَ قَالَ النَّبِيُّ ﷺ لِلْمُتَلاَعِنَيْنِ حِسَابُكُمَا عَلَى اللَّهِ أَحَدُكُمَا كَاذِبٌ لاَ سَبِيلَ لَكَ عَلَيْهَا قَالَ مَالِي قَالَ لاَ مَالَ لَكَ إِنْ كُنْتَ صَدَقْتَ عَلَيْهَا فَهْوَ بِمَا اسْتَحْلَلْتَ مِنْ فَرْجِهَا وَإِنْ كُنْتَ كَذَبْتَ عَلَيْهَا فَذَاكَ أَبْعَدُ لَكَ قَالَ سُفْيَانُ حَفِظْتُهُ مِنْ عَمْرٍو وَقَالَ أَيُّوبُ سَمِعْتُ سَعِيدَ بْنَ جُبَيْرٍ قَالَ قُلْتُ لاِبْنِ عُمَرَ رَجُلٌ لاَعَنَ امْرَأَتَهُ فَقَالَ بِإِصْبَعَيْهِ وَفَرَّقَ سُفْيَانُ بَيْنَ إِصْبَعَيْهِ السَّبَّابَةِ وَالْوُسْطَى فَرَّقَ النَّبِيُّ ﷺ بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ وَقَالَ اللَّهُ يَعْلَمُ إِنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ ثَلاَثَ مَرَّاتٍ قَالَ سُفْيَانُ حَفِظْتُهُ مِنْ عَمْرٍو وَأَيُّوبَ كَمَا أَخْبَرْتُكَ  

I asked Ibn ʿUmar, "(What is the verdict if) a man accuses his wife of illegal sexual intercourse?" Ibn ʿUmar said, "The Prophet ﷺ separated (by divorce) the couple of Bani Al-Ajlan, and said, (to them), 'Allah knows that one of you two is a liar; so will one of you repent?' But both of them refused. He again said, 'Allah knows that one of you two is a liar; so will one of you repent?' But both of them refused. So he separated them by divorce." (Aiyub, a sub-narrator said: ʿAmr bin Dinar said to me, "There is something else in this Hadith which you have not mentioned. It goes thus: The man said, 'What about my money (i.e. the Mahr that I have given to my wife)?' It was said, 'You have no right to restore any money, for if you have spoken the truth (as regards the accusation), you have also consummated your marriage with her; and if you have told a lie, you are less rightful to have your money back.' ")  

قُلْتُ لاِبْنِ عُمَرَ رَجُلٌ قَذَفَ امْرَأَتَهُ فَقَالَ فَرَّقَ النَّبِيُّ ﷺ بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ وَقَالَ اللَّهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ فَأَبَيَا وَقَالَ اللَّهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبُ فَأَبَيَا فَقَالَ اللَّهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ فَأَبَيَا فَفَرَّقَ بَيْنَهُمَا قَالَ أَيُّوبُ فَقَالَ لِي عَمْرُو بْنُ دِينَارٍ إِنَّ فِي الْحَدِيثِ شَيْئًا لاَ أَرَاكَ تُحَدِّثُهُ قَالَ قَالَ الرَّجُلُ مَالِي قَالَ قِيلَ لاَ مَالَ لَكَ إِنْ كُنْتَ صَادِقًا فَقَدْ دَخَلْتَ بِهَا وَإِنْ كُنْتَ كَاذِبًا فَهْوَ أَبْعَدُ مِنْكَ  

"I said to Ibn 'Umar: 'A man accused his wife.' He said: 'The Messenger of Allah separated the couple from Banu 'Ajlan and said: Allah knows that one of you is lying, so will either of you repent? He said that to them three times and they did not respond, then he separated them.'" (One of the narrators) Ayyub said: "Amr bin Dinar said: 'In this Hadith there is something that I think you are not narrating.' He said: 'The man said: My wealth. He said: You are not entitled to any wealth. If you are telling the truth, you have consummated the marriage with her, and if you are lying then you are even less entitled to it.'"  

قُلْتُ لاِبْنِ عُمَرَ رَجُلٌ قَذَفَ امْرَأَتَهُ قَالَ فَرَّقَ رَسُولُ اللَّهِ ﷺ بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ وَقَالَ اللَّهُ يَعْلَمُ إِنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ قَالَ لَهُمَا ثَلاَثًا فَأَبَيَا فَفَرَّقَ بَيْنَهُمَا قَالَ أَيُّوبُ وَقَالَ عَمْرُو بْنُ دِينَارٍ إِنَّ فِي هَذَا الْحَدِيثِ شَيْئًا لاَ أَرَاكَ تُحَدِّثُ بِهِ قَالَ قَالَ الرَّجُلُ مَالِي قَالَ لاَ مَالَ لَكَ إِنْ كُنْتَ صَادِقًا فَقَدْ دَخَلْتَ بِهَا وَإِنْ كُنْتَ كَاذِبًا فَهِيَ أَبْعَدُ مِنْكَ  

I said to Ibn ʿUmar, "If a man accuses his wife of illegal sexual intercourse (what is the judgment)?" He said, "Allah's Prophet separated the couple of Bani 'Ajlan (when the husband accused his wife for an illegal sexual intercourse). The Prophet ﷺ said, 'Allah knows that one of you two IS a liar; so will one of you repent?' But they refused. He then again said, 'Allah knows that one of you two is a liar; so will one of you repent?' But they refused, whereupon he separated them by divorce." Aiyub (a subnarrator) said: ʿAmr bin Dinar said to me, "In the narration there is something which I do not see you mentioning, i.e. the husband said, "What about my money (Mahr)?' The Prophet ﷺ said, "You are not entitled to take back money, for if you told the truth you have already entered upon her (and consummated your marriage with her) and if you are a liar then you are less entitled to take it back. (Using translation from Bukhārī 5349)   

فَرَّقَ نَبِيُّ اللهِ ﷺ بَيْنَ أَخَوَيْ بَنِي الْعَجْلَانِ ثُمَّ قَالَ «وَاللهُ أَعْلَمُ إِنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ» قَالَهَا ثَلَاثًا فَأَبَيَا فَفَرَّقَ بَيْنَهُمَا قَالَ أَيُّوبُ وَقَالَ لِي عَمْرُو بْنُ دِينَارٍ إِنَّ فِي هَذَا الْحَدِيثِ شَيْئًا لَا أَرَاكَ تُحَدِّثُ بِهِ قَالَ قَالَ الرَّجُلُ مَالِي قَالَ لَا مَالَ لَكَ إِنْ كُنْتَ صَادِقًا فَقَدْ دَخَلْتَ بِهَا وَإِنْ كُنْتَ كَاذِبًا فَهِيَ أَبَعْدُ مِنْكَ
