Abu Hurairah (May Allah be pleased with
him) reported: Messenger of Allah (PBUH)
said, "On every joint of man, there is
charity, on everyday when the sun rises:
doing justice between two men is charity,
and assisting a man to ride an animal or to
load his luggage on it is charity; and a good
word is charity, every step which one takes
towards (the mosque for) Salat is charity,
and removing harmful things from the way
is charity". [Al-Bukhari and Muslim]
