قَوْلُهُ تَعَالَى: {وَالَّذِينَ يَرْمُونَ أَزْوَاجَهَمْ وَلَمْ يَكُنْ لَهُمْ شُهَدَاءُ إِلَّا أَنْفُسُهُمْ} [النور: 6]

"I heard Sa'eed bin Jubair say: 'I was asked about the two who engage in Li'an during the governorship of Ibn Az-Zubair - should they be separated? I did not know what to say, so I got up and went to the house of Ibn 'Umar and said: "O Abu 'Abdur-Rahman, should the two who engage in Li'an be separated?" He said: "Yes, Subhan Allah! The first one who asked about that was so-and-so the son of so-and-so who said: 'O Messenger of Allah, what do you think if a man among us sees his wife committing immoral actions, and if he speaks of it, he will be speaking of a grave matter, but if he keeps quiet, he will be keeping quiet about a grave matter?' He did not answer him, then after that, he came to him and said: 'I was tried with the matter that I asked you about, so Allah, the Mighty and Sublime, revealed these Verses in Surat An-Nur.: 'And for those who accuse their wives' until he reached: 'And the fifth (testimony) should be that the Wrath of Allah be upon her if he (her husband) speaks the truth.' So he started with the man, exhorting him, reminding him, and telling him that the punishment in this world was less severe than the punishment in the Hereafter. He said: 'By the One Who sent you with the truth, I am not lying.' Then he turned to the woman and exhorted her and reminded her. She said: 'By the One Who sent you with the truth, he is lying.' So he started with the man, and he bore witness four times by Allah that he was telling the truth, and the fifth time (he invoked) the curse of Allah upon himself if he was lying. Then he turned to the woman and she bore witness four times by Allah that he was lying, and the fifth time (she invoked) the wrath of Allah upon herself if he was telling the truth. Then he separated them."'" (Using translation from Nasāʾī 3473)   

سَأَلْتُ ابْنَ عُمَرَ فَقُلْتُ يَا أَبَا عَبْدِ الرَّحْمَنِ الْمُتَلَاعِنَيْنِ يُفَرَّقُ بَيْنَهُمَا؟ قَالَ سُبْحَانَ اللهِ نَعَمْ إِنَّ أَوَّلَ مَنْ سَأَلَ عَنْ ذَلِكَ فُلَانٌ قَالَ يَا رَسُولَ اللهِ أَرَأَيْتَ لَوْ أَنَّ أَحَدَنَا رَأَى امْرَأَتَهُ عَلَى فَاحِشَةٍ كَيْفَ يَصْنَعُ؟ إِنْ سَكَتَ سَكَتَ عَلَى أَمْرٍ عَظِيمٍ وَإِنْ تَكَلَّمَ فَمِثْلُ ذَلِكَ فَسَكَتَ رَسُولُ اللهِ ﷺ وَلَمْ يُجِبْهُ فَقَامَ لِحَاجَتِهِ فَلَمَّا كَانَ بَعْدَ ذَلِكَ أَتَى رَسُولَ اللهِ ﷺ فَقَالَ إِنَّ الَّذِي سَأَلْتُكَ عَنْهُ قَدِ ابْتُلِيتُ بِهِ قَالَ فَأَنْزَلَ اللهُ تَعَالَى هَذِهِ الْآيَاتِ فِي سُورَةِ النُّورِ {وَالَّذِينَ يَرْمُونَ أَزْوَاجَهُمْ} [النور 6] حَتَّى خَتَمَ الْآيَاتِ فَدَعَا الرَّجُلَ فَتَلَاهُنَّ عَلَيْهِ وَذَكَّرَهُ بِاللهِ تَعَالَى وَأَخْبَرَهُ أَنَّ عَذَابَ الدُّنْيَا أَهْوَنُ مِنْ عَذَابِ الْآخِرَةِ فَقَالَ وَالَّذِي بَعَثَكَ بِالْحَقِّ مَا كَذَبْتُ عَلَيْهَا ثُمَّ دَعَا الْمَرْأَةَ فَوَعَظَهَا وَذَكَّرَهَا وَأَخْبَرَهَا بِأَنَّ عَذَابَ الدُّنْيَا أَهْوَنُ مِنْ عَذَابِ الْآخِرَةِ فَقَالَتْ وَالَّذِي بَعَثَكَ بِالْحَقِّ إِنَّهُ لَكَاذِبٌ فَدَعَاالرَّجُلَ فَشَهِدَ أَرْبَعَ شَهَادَاتٍ بِاللهِ إِنَّهُ لَمِنَ الصَّادِقِينَ وَالْخَامِسَةَ أَنَّ لَعْنَةَ اللهِ عَلَيْهِ إِنْ كَانَ مِنَ الْكَاذِبِينَ ثُمَّ دَعَا بِالْمَرْأَةِ فَشَهِدَتْ أَرْبَعَ شَهَادَاتٍ بِاللهِ إِنَّهُ لَمِنَ الْكَاذِبِينَ وَالْخَامِسَةَ أَنَّ غَضَبَ اللهِ عَلَيْهَا إِنْ كَانَ مِنَ الصَّادِقِينَ ثُمَّ فَرَّقَ بَيْنَهُمَا
