وَحَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَزُهَيْرُ بْنُ حَرْبٍ قَالُوا حَدَّثَنَا
إِسْمَاعِيلُ، - يَعْنُونَ ابْنَ عُلَيَّةَ - عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله
عليه وسلم بِهَذَا وَلَمْ يَذْكُرْ فِي الْحَدِيثِ مُحَمَّدٌ رَسُولُ اللَّهِ
