A father borrowing with interest, engaging in unlawful transactions, and accumulating large debts with the intention of not repaying them are major sins through which Allah annihilates wealth. Building a mosque with lawful money is rewarded, for a good deed is not nullified by a bad one. However, building it with unlawful money is not accepted by Allah. The father must spend on his family in a reasonable manner and should not be absent from his wife for more than six months unless there is a valid excuse. If a son advises his father and the father does not respond, there is no sin upon the son.
