أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ أَبُو سَعِيدٍ الأَشَجُّ، قَالَ حَدَّثَنِي عُقْبَةُ بْنُ خَالِدٍ، قَالَ حَدَّثَنَا شُعْبَةُ، وَابْنُ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ صَلَّيْتُ خَلْفَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ - رضى الله عنهم - فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ يَجْهَرُ بِـ { بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ } .
