البيهقي:٦٧٣٤ – أَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ الْفَضْلِ الْقَطَّانُ أنبأ عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يَعْقُوبُ بْنُ سُفْيَانَ ثنا عَبْدُ اللهِ بْنُ عُثْمَانَ أنبأ عَبْدُ اللهِ أنبأ مَعْمَرٌ عَنْ عَلِيِّ بْنِ زَيْدٍ أَنَّ ابْنَ عَبَّاسٍ لَمَّا دَفَنَ زَيْدَ بْنَ ثَابِتٍ حَثَا عَلَيْهِ التُّرَابَ ثُمَّ قَالَ هَكَذَا يُدْفَنُ الْعِلْمُ فَحَدَّثْتُ بِهِ عَلِيَّ بْنَ الْحُسَيْنِ فَقَالَ

وَابْنُ عَبَّاسٍ وَاللهِ لَقَدْ دُفِنَ بِهِ عِلْمٌ كَثِيرٌ
