It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A dinar that you gave to a poor person, a dinar that you spent on (freeing) a neck (a slave), a dinar that you spent in the path of Allah, and a dinar that you spent on your family: the best of them is the dinar that you spent on your family."
