Allah's Apostle (ﷺ) said to me: Don't consider anything insignificant out of good things even if it is that you meet your brother with a cheerful countenance.
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 صلى الله عليه وسلم ‏
"‏ لاَ تَحْقِرَنَّ مِنَ الْمَعْرُوفِ شَيْئًا وَلَوْ أَنْ تَلْقَى أَخَاكَ بِوَجْهٍ طَلْقٍ ‏"‏ ‏.‏
