حَدَّثَنَا الرَّبِيعُ بْنُ نَافِعٍ، حَدَّثَنَا أَبُو إِسْحَاقَ، - يَعْنِي الْفَزَارِيَّ - عَنْ أَبِي إِسْحَاقَ، عَنْ مُحَارِبِ بْنِ دِثَارٍ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ يَزِيدَ، يَقُولُ عَلَى الْمِنْبَرِ حَدَّثَنِي الْبَرَاءُ، أَنَّهُمْ كَانُوا يُصَلُّونَ مَعَ رَسُولِ اللَّهِ ﷺ فَإِذَا رَكَعَ رَكَعُوا وَإِذَا قَالَ
" سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ " . لَمْ نَزَلْ قِيَامًا حَتَّى يَرَوْهُ قَدْ وَضَعَ جَبْهَتَهُ بِالأَرْضِ ثُمَّ يَتَّبِعُونَهُ ﷺ .
