It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: Charity is obligatory on every joint of a person in the morning. This seemed very difficult to the Muslims. The Holy Prophet (peace and blessings of Allah be upon him) said: Greeting Allah’s servants with peace is also charity, removing something harmful from the path is also charity, enjoining good and forbidding evil is also charity. He mentioned some other things as well, which I do not remember.
