Hilal bin Umaiyya accused his wife of illegal sexual intercourse and came to the Prophet ﷺ to bear witness (against her), (taking the oath of Lian). The Prophet ﷺ was saying, "Allah knows that either of you is a liar. Will anyone of you repent (to Allah)?" Then the lady got up and gave her witness.  

أَنَّ هِلاَلَ بْنَ أُمَيَّةَ قَذَفَ امْرَأَتَهُ فَجَاءَ فَشَهِدَ وَالنَّبِيُّ ﷺ يَقُولُ إِنَّ اللَّهَ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ ثُمَّ قَامَتْ فَشَهِدَتْ  

Allah knows that one of you is a liar. Is there one to repent among you?  

فَرَّقَ رَسُولُ اللَّهِ ﷺ بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ وَقَالَ اللَّهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ
