"Every good is charity. Indeed among the good is to meet your brother with a smiling face, and to pour what is left in your bucket into the vessel of your brother."  

قَالَ رَسُولُ اللَّهِ ﷺ كُلُّ مَعْرُوفٍ صَدَقَةٌ وَإِنَّ مِنَ الْمَعْرُوفِ أَنْ تَلْقَى أَخَاكَ بِوَجْهٍ طَلْقٍ وَأَنْ تُفْرِغَ مِنْ دَلْوِكَ فِي إِنَاءِ أَخِيكَ وَفِي الْبَابِ عَنْ أَبِي ذَرٍّ
