حَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، حَدَّثَنَا أَبُو عَامِرٍ – يَعْنِي الْخَزَّازَ – عَنْ أَبِي عِمْرَانَ الْجَوْنِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ الصَّامِتِ، عَنْ أَبِي ذَرٍّ، قَالَ: قَالَ لِيَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: لَا تَحْقِرَنَّ مِنَ الْمَعْرُوفِ شَيْئًا، وَلَوْ أَنْ تَلْقَى أَخَاكَ بِوَجْهٍ طَلْقٍ
