حَدَّثَنَا يَحْيَى عَنِ الْأَعْمَشِ عَنْ شَقِيقٍ عَنْ عَبْدِ اللَّهِ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا كَانُوا ثَلَاثَةً فَلَا يَتَنَاجَى اثْنَانِ دُونَ صَاحِبِهِمَا فَإِنَّ ذَلِكَ يَحْزُنُهُ
مسند امام احمد بن حنبل · Hadith 4093
It was narrated from 'Abdullah that the Prophet (PBUH) said: "If you are three, two should not converse (privately) to the exclusion of their companion, because that makes him sad."
