الزهد لأحمد:٢٢٧٨ – حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَنْبَأَنَا حَرِيزُ بْنُ عُثْمَانَ حَدَّثَنَا سُلَيْمَانُ بْنُ سُمَيْرٍ قَالَ سَمِعْتُ كَثِيرَ بْنَ مُرَّةَ يَقُولُ «لَا تَحَدَّثِ الْحِكْمَةَ عِنْدَ السُّفَهَاءِ فَيُكَذِّبُوكَ وَلَا تَحَدَّثِ الْبَاطِلَ عِنْدَ الْحُكَمَاءِ فَيَمْقُتُوكَ وَلَا تَمْنَعِ الْعِلْمَ أَهْلَهُ فَتَأْثَمَ وَلَا

تُحَدِّثْهُ غَيْرَ أَهْلِهِ فَتُجَهَّلَ إِنَّ عَلَيْكَ فِي عِلْمِكَ حَقًّا كَمَا عَلَيْكَ فِي مَالِكَ حَقًا»
