البيهقي:٦١٨٧ – أَخْبَرَنَا أَبُو بَكْرٍ أَحْمَدُ بْنُ إِبْرَاهِيمَ بْنِ مُحَمَّدٍ الْأَصْبَهَانِيُّ أنبأ أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِمْرَانَ الْأَخْبَارِيُّ بِبَغْدَادَ ثنا عَلِيُّ بْنُ عَبْدِ اللهِ بْنِ الْفَضْلِ بْنِ الْأَسْوَدِ بِالْبَصْرَةِ ثنا عَلِيُّ بْنُ عَيَّاشٍ ثنا عَلِيُّ بْنُ عَاصِمٍ عَنْ دَاوُدَ بْنِ أَبِي هِنْدَ عَنِ الشَّعْبِيِّ عَنْ جَابِرِ بْنِ عَبْدِ اللهِ قَالَ مَضَتِ السُّنَّةُ
