It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The best dinar a man spends is the dinar he spends on his family, the dinar a man spends on his riding animal in the path of Allah, and the dinar a man spends on his companions in the path of Allah." Abu Qilabah (may Allah have mercy on him) said: He (peace and blessings be upon him) began with the family. Which man is greater in reward than a man who spends on his young family, through which Allah Almighty provides them with food and Allah Almighty benefits them by it? Imam Muslim (may Allah have mercy on him) narrated it in the Sahih from Abu al-Rabi'.
