Sahih Adab al-Mufrad

688/891- From Abu Dharr, attributing it to the Prophet (he said: then he said after that: I do not know except that he attributed it to the Prophet): "Pouring from your bucket into your brother's bucket is charity, commanding good and forbidding evil is charity, your smiling in your brother's face is charity, removing a stone, thorn, or bone from the people's path is charity for you, and guiding a man in a land of misguidance is charity."
