It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The dinar that you spend in the way of Allah, and the dinar that you distribute among the needy, and the dinar with which you free a slave, and the dinar that you spend on your family—among these, the greatest reward will be for the dinar that you spend on your family.
