البيهقي:٨٢٧أَخْبَرَنَا أَبُو الْحَسَنِ عَلِيُّ بْنُ مُحَمَّدٍ الْمُقْرِئُ ثنا الْحَسَنُ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ ثنا يُوسُفُ بْنُ يَعْقُوبَ الْقَاضِي ثنا نَصْرُ بْنُ عَلِيٍّ وَمُحَمَّدُ بْنُ أَبِي بَكْرٍ قَالَا ثنا الْحَارِثُ بْنُ وَجِيهٍ الرَّاسِبِيُّ ثنا مَالِكُ بْنُ دِينَارٍ عَنْ مُحَمَّدِ بْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ
