[Machine] "Do not speak falsehood in front of the wise, as they will despise you. Do not speak wisdom to the foolish, as they will deny you. Do not prevent knowledge from those who deserve it, for you would commit a sin. And do not place it in the hands of those who are not qualified, as you would be disregarded. Know that you have a responsibility towards your knowledge, just as you have a responsibility towards your wealth."  

الدارمي:٣٩٠أَخْبَرَنَا يُوسُفُ بْنُ مُوسَى حَدَّثَنَا إِسْحَاقُ بْنُ سُلَيْمَانَ حَدَّثَنَا حَرِيزٌ عَنْ سَلْمَانَ بْنِ سُمَيْرٍ عَنْ كَثِيرِ بْنِ مُرَّةَ قَالَ

«لَا تُحَدِّثِ الْبَاطِلَ الْحُكَمَاءَ فَيَمْقُتُوكَ وَلَا تُحَدِّثِ الْحِكْمَةَ لِلسُّفَهَاءِ فَيُكَذِّبُوكَ وَلَا تَمْنَعِ الْعِلْمَ أَهْلَهُ فَتَأْثَمَ وَلَا تَضَعْهُ فِي غَيْرِ أَهْلِهِ فَتُجَهَّلَ إِنَّ عَلَيْكَ فِي عِلْمِكَ حَقًّا كَمَا أَنَّ عَلَيْكَ فِي مَالِكَ حَقًّا»
