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.  

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

Your account is with Allah. One of you must be a liar. You have now no right over this woman. He said: Messenger of Allah, what about my wealth (dower that I paid her at the time of marriage)? He said: You have no claim to wealth. If you tell the truth, it (dower) is the recompense for your having had the right to intercourse with her, and if you tell a lie against her, it is still more remote from you than she is. Zuhair said in his narration: Sufyan reported to us on the authority of 'Amr that he had heard Sa'id b Jubair saying: I heard Ibn Umar (Allah be pleased with them) saying that Messenger of Allah ﷺ had said it.  

قَالَ رَسُولُ اللَّهِ ﷺ لِلْمُتَلاَعِنَيْنِ حِسَابُكُمَا عَلَى اللَّهِ أَحَدُكُمَا كَاذِبٌ لاَ سَبِيلَ لَكَ عَلَيْهَا قَالَ يَا رَسُولَ اللَّهِ مَالِي قَالَ لاَ مَالَ لَكَ إِنْ كُنْتَ صَدَقْتَ عَلَيْهَا فَهْوَ بِمَا اسْتَحْلَلْتَ مِنْ فَرْجِهَا وَإِنْ كُنْتَ كَذَبْتَ عَلَيْهَا فَذَاكَ أَبْعَدُ لَكَ مِنْهَا قَالَ زُهَيْرٌ فِي رِوَايَتِهِ حَدَّثَنَا سُفْيَانُ عَنْ عَمْرٍو سَمِعَ سَعِيدَ بْنَ جُبَيْرٍ يَقُولُ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ  

I asked Ibn 'Umar about the two who engage in Li'an. He said: 'The Messenger of Allah said to the two who engaged in Li'an: Your reckoning will be with Allah. One of you is lying, and you cannot stay with her. He said: O Messenger of Allah, my wealth! He said: You are not entitled to any wealth. If you are telling the truth about her, then it is in return for having been allowed intimacy with her, and if you are lying then you are even less entitled to it."  

سَأَلْتُ ابْنَ عُمَرَ عَنِ الْمُتَلاَعِنَيْنِ فَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ لِلْمُتَلاَعِنَيْنِ حِسَابُكُمَا عَلَى اللَّهِ أَحَدُكُمَا كَاذِبٌ وَلاَ سَبِيلَ لَكَ عَلَيْهَا قَالَ يَا رَسُولَ اللَّهِ مَالِي قَالَ لاَ مَالَ لَكَ إِنْ كُنْتَ صَدَقْتَ عَلَيْهَا فَهُوَ بِمَا اسْتَحْلَلْتَ مِنْ فَرْجِهَا وَإِنْ كُنْتَ كَذَبْتَ عَلَيْهَا فَذَاكَ أَبْعَدُ لَكَ  

[Machine] The Messenger of Allah ﷺ said to the two curse-invokers, "Your account is with Allah. One of you is a liar, and there is no way for you to avoid it." One of them said, "O Messenger of Allah, what is mine is mine." He ﷺ said, "If you are truthful about it, then it is what you have legally acquired from her private part. But if you are lying about it, then it is further away from you than her (private part). This was reported in the authentic Hadith by Sufyan, as it has been transmitted to us from Muhammad ibn Zaid, from Sa'id ibn Jubayr, from Ibn 'Umar, from the Prophet ﷺ , who said, "When two curse-invokers separate, they will never come together again."  

قَالَ رَسُولُ اللهِ ﷺ لِلْمُتَلَاعِنَيْنِ حِسَابُكُمَا عَلَى اللهِ أَحَدُكُمَا كَاذِبٌ لَا سَبِيلَ لَكَ عَلَيْهَا فَقَالَ يَا رَسُولَ اللهِ مَالِي مَالِي قَالَ إِنْ كُنْتَ صَدَقْتَ عَلَيْهَا فَهُوَ بِمَا اسْتَحْلَلْتَ مِنْ فَرْجِهَا وَإِنْ كُنْتَ كَذَبْتَ عَلَيْهَا فَهُوَ أَبْعَدُ لَكَ مِنْهُ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ سُفْيَانَ كَمَا مَضَى وَرُوِّينَا عَنْ مُحَمَّدِ بْنِ زَيْدٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عُمَرَ ؓ عَنِ النَّبِيِّ ﷺ قَالَ الْمُتَلَاعِنَانِ إِذَا تَفَرَّقَا لَا يَجْتَمِعَانِ أَبَدًا
