عَنْ أَبِي ذَرٍّ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ لَا تَحْقِرَنَّ مِنَ الْمَعْرُوفِ شَيْئًا فَإِنْ لَمْ تَجِدْ فَالْقَ أَخَاكَ بِوَجْهٍ طَلْقٍ
It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Do not consider any good deed insignificant, so if you have nothing to give, then meet your brother with a cheerful and open face.
