البيهقي:٣١٥٧ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أَخْبَرَنِي أَبُو الْحَسَنِ الْعَنَزِيُّ ثنا عُثْمَانُ بْنُ سَعِيدٍ ثنا مُوسَى بْنُ إِسْمَاعِيلَ ثنا هَمَّامٌ عَنْ قَتَادَةَ عَنْ أَبِي مِجْلَزٍ قَالَ صَلَّيْتُ مَعَ ابْنِ عُمَرَ صَلَاةَ الصُّبْحِ فَلَمْ يَقْنُتْ فَقُلْتُ لِابْنِ عُمَرَ لَا أَرَاكَ تَقْنُتُ قَالَ لَا أَحْفَظُهُ عَنْ أَحَدٍ مِنْ أَصْحَابِنَا قَالَ الشَّيْخُ نِسْيَانُ بَعْضِ الصَّحَابَةِ أَوْ غَفْلَتُهُ

عَنْ بَعْضِ السُّنَنِ لَا يَقْدَحُ فِي رِوَايَةِ مَنْ حَفِظَهُ وَأَثْبَتَهُ
