أحمد:٤٨٧٤حَدَّثَنَا يَزِيدُ أَخْبَرَنَا مُحَمَّدُ بْنُ إِسْحَاقَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ

نَهَى رَسُولُ اللهِ ﷺ أَنْ يَتَنَاجَى اثْنَانِ دُونَ الثَّالِثِ إِذَا لَمْ يَكُنْ مَعَهُمْ غَيْرُهُمْ قَالَ وَنَهَى النَّبِيُّ ﷺ أَنْ يَخْلُفَالرَّجُلُ الرَّجُلَ فِي مَجْلِسِهِ وَقَالَ إِذَا رَجَعَ فَهُوَ أَحَقُّ بِهِ
