Thawban narrated that the Messenger of Allah (ﷺ) said: "The most virtuous of the Dinar is the Dinar spent by a man on his dependants, and the Dinar spent by a man on his beast in the Cause of Allah, and the Dinar spent by a man on his companions in the Cause of Allah." Abu Qilabah (one of the narrators) said: " He began with the dependants." Then he said: "And which man is greater in reward than a man who spends upon his depandants, having little ones by which Allah causes him to abstain (from the unlawful) and by which Allah enriches him."
