البيهقي:١٩٥٧ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو بَكْرِ بْنُ الْحَسَنِ وَأَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو قَالُوا ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا هَارُونُ بْنُ سُلَيْمَانَ الْأَصْبَهَانِيُّ ثنا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ أَبَانَ بْنِ يَزِيدَ عَنْ قَتَادَةَ
