Sa’d bin Jubair said I asked Ibn ‘Umar A man accused his wife of adultery? He said “The Apostle of Allaah ﷺ separated the brother and the sister of Banu Al ‘Ajilan (i.e., husband and wife). He said Allaah knows that one of you is a liar, will one of you repent? He repeated these words three times, but they refused. So he separated them from each other.  

قُلْتُ لاِبْنِ عُمَرَ رَجُلٌ قَذَفَ امْرَأَتَهُ قَالَ فَرَّقَ رَسُولُ اللَّهِ ﷺ بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ وَقَالَ اللَّهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ يُرَدِّدُهَا ثَلاَثَ مَرَّاتٍ فَأَبَيَا فَفَرَّقَ بَيْنَهُمَا

(Using translation from Abū Dāʾūd 2258)  

قُلْتُ لِابْنِ عُمَرَ رَجُلٌ قَذَفَ امْرَأَتَهُ فَقَالَ فَرَّقَ رَسُولُ اللهِ ﷺ بَيْنَ أَخَوَيْ بَنِي الْعَجْلَانِ وَقَالَ اللهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ؟ فَأَبَيَا فَرَدَّدَهُمَا ثَلَاثَ مَرَّاتٍ فَأَبَيَا فَفَرَّقَ بَيْنَهُمَا  

[Machine] The Messenger of Allah ﷺ separated between the two brothers from the Banu Al-Ajlan tribe and said, "One of you is a liar. Are there any witnesses among you?" He repeated this three times.  

فَرَّقَ رَسُولُ اللهِ ﷺ بَيْنَ أَخَوَيْ بَنِي الْعَجْلَانِ وَقَالَ إِنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَاتَائِبٌ؟ ثَلَاثًا  

"إِنَّ الله يَعْلَمُ أنَّ أحَدَكُمَا كَاذِبٌ! فَهَلْ مِنكُمَا تَائِبٌ؟ قَالهُ لِلمُتَلاعِنَين".
