Sayyidina Thawban (RA) reported that the Prophet (SAW) said, “The most excellent of dinars is the dinar a man spends on his family, and the dinar he spends on his animal in Allah’s path, and the dinar a man spends on his companions in the path of Allah.” Abu Qilabah said that he began with the family. Then, the Prophet (SAW) said, “Which of the men can be more deserving of reward than the man who spends on his family having young children whom Allah protects through him and makes them independent.”
[Muslim 994]
