البيهقي:٢٠٤١٦أَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ الْفَضْلِ الْقَطَّانُ أنبأ أَبُو سَهْلِ بْنُ زِيَادٍ الْقَطَّانُ ثنا إِسْحَاقُ بْنُ الْحَسَنِ الْحَرْبِيُّ ثنا عَفَّانُ ثنا مَهْدِيُّ بْنُ مَيْمُونٍ ثنا غَيْلَانُ بْنُ جَرِيرٍ قَالَ قَالَ مُطَرِّفُ بْنُ عَبْدِ اللهِ احْتَرِسُوا مِنَ النَّاسِ بِسُوءِ الظَّنِّ قَالَ الشَّيْخُ رَحِمَهُ اللهُ وَرُوِيَ ذَلِكَ
