حَدَّثَنَا أَبُو مَعْمَرٍ عَبْدُ اللَّهِ بْنُ عَمْرٍو، قَالَ حَدَّثَنَا عَبْدُ الْوَارِثِ، قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ صُهَيْبٍ، عَنْ أَنَسٍ، قَالَ أُقِيمَتِ الصَّلاَةُ وَالنَّبِيُّ صلى الله عليه وسلم يُنَاجِي رَجُلاً فِي جَانِبِ الْمَسْجِدِ، فَمَا قَامَ إِلَى الصَّلاَةِ حَتَّى نَامَ الْقَوْمُ.
