ahmad:6024ʿAlī b. ʿAyyāsh > Shuʿayb b. Abū Ḥamzah > Nāfiʿ > ʿAbdullāh b. ʿUmar

[Machine] Narrated by the Prophet (PBUH): When three people gather, two of them should not engage in a private conversation excluding the third person. And no one among you should get up and leave his brother sitting in the assembly, then join back in.  

أحمد:٦٠٢٤حَدَّثَنَا عَلِيُّ بْنُ عَيَّاشٍ حَدَّثَنَا شُعَيْبُ بْنُ أَبِي حَمْزَةَ عَنْ نَافِعٍ عَنْ عَبْدِ اللهِ بْنِ عُمَرَ

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا اجْتَمَعَ ثَلَاثَةٌ فَلَا يَتَنَاجَى اثْنَانِ دُونَ الثَّالِثِ وَلَا يُقِيمَنَّ أَحَدُكُمْ أَخَاهُ مِنْ مَجْلِسِهِ ثُمَّ يَجْلِسُ فِيهِ
