Ibn 'Umar (Allah be pleased with them) said that Messenger of Allah ﷺ effected separation between the two members of Banu al-'Ajlan, and said: Allah knows that one of you is a liar. Is there one to repent among you?
وَحَدَّثَنِي أَبُو الرَّبِيعِ الزَّهْرَانِيُّ، حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عُمَرَ، قَالَ فَرَّقَ رَسُولُ اللَّهِ ﷺ بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ وَقَالَ
" اللَّهُ يَعْلَمُ أَنَّ أَحَدَكُمَا كَاذِبٌ فَهَلْ مِنْكُمَا تَائِبٌ " .
