Arabic hadith text
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا ابْنُ الْمُنْكَدِرِ، عَنْ أَبِيهِ، عَنْ جَابِرٍ قَالَ‏:‏ قَالَ رَسُولُ اللهِ صلى الله عليه وسلم‏:‏ كُلُّ مَعْرُوفٍ صَدَقَةٌ، إِنَّ مِنَ الْمَعْرُوفِ أَنْ تَلْقَى أَخَاكَ بِوَجْهٍ طَلْقٍ، وَأَنْ تُفْرِغَ مِنْ دَلْوِكَ فِي إِنَاءِ أَخِيكَ‏.‏
Translation

Jabir reported that the Messenger of Allah, may Allah bless himand grant him peace, said, "Every act of kindness is sadaqa. Part of kindnessis that you offer your brother a cheerful face and you pour some of yourbucket into his water vessel."
