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."
عن أبي هريرة -رضي الله عنه- قال: قال رسول الله -صلى الله عليه وسلم-: «دينار أنفقته في سبيل الله، ودينار أنفقته في رقبة، ودينار تصدقت به على مسكين، ودينار أنفقته على أهلك، أعظمها أجرًا الذي أنفقته على أهلك».
شرح الحديث :
The Prophet (may Allah's peace and blessings be upon him) clarified that the channels of spending in good causes are many, including spending in Jihad for the sake of Allah, in manumitting slaves, on the needy, and on one's family and dependents. The best of these is the spending on one's family because it is obligatory. The reward for obligatory spending is greater than that for recommended spending.
