البيهقي:٢٤١٥ – أَخْبَرَنَا أَبُو طَاهِرٍ الْفَقِيهُ أنبأ أَبُو بَكْرٍ مُحَمَّدُ بْنُ الْحُسَيْنِ الْقَطَّانُ أنبأ مُحَمَّدُ بْنُ يَزِيدَ السُّلَمِيُّ ثنا بَدَلُ بْنُ الْمُحَبَّرِ أَبُو الْمُنِيرِ الْيَرْبُوعِيُّ ثنا شُعْبَةُ عَنْ قَتَادَةَ قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ قَالَ صَلَّيْتُ

خَلْفَ رَسُولِ اللهِ ﷺ وَخَلْفَ أَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ ؓ فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ قَالَ بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ  

أَخْرَجَهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ مُوسَى وَبِنْدَارٍ عَنْ مُحَمَّدِ بْنِ جَعْفَرٍ غُنْدَرٍ عَنْ شُعْبَةَ وَقَالَ فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ يَقْرَأُ بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ وَبِهَذَا اللَّفْظِ
