Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "A dinar you spend in the cause of Allah, a dinar you spend on (freeing) a slave, a dinar you give in charity to a needy person, and a dinar you spend on your family; the greatest in reward is the one you spend on your family."
