How can a person manage their salary, save from it, and give charity to their relatives?

Your expenditure on your wife and daughter is among the best forms of charity. Abu Hurairah narrated that the Prophet (peace be upon him) said: «A dinar you spend in the way of Allah, a dinar you spend in freeing a slave, a dinar you give in charity to a poor person, and a dinar you spend on your family—the greatest in reward is the one you spend on your family.» Your expenditure should be moderate, neither extravagant nor stingy, as Allah Almighty says: «And those who, when they spend, do not spend extravagantly nor are stingy, but are between that [justly] moderate.»
