The Ruling on a Son Consuming His Father’s Money from Usury

Question:
I am a young man, twenty years old. My father works in trade, but at times he takes loans from the bank and then repays them to the bank along with the interest. Sometimes I perform some tasks for him. The question is: Is it permissible for me to eat from, or take from, my father’s money?

Answer:
As long as your father has other income from lawful sources, but he may err by taking a loan from the bank, there is no blame on you for eating with your father. You should only assist him in good and advise him so that he does not return to taking loans from the bank with interest. You can say to him: “This is forbidden and not permissible for you,” perhaps Allah will guide him through your efforts. Or you can tell your uncle or your older brothers to speak to him in a good manner, so that Allah may guide him and he accepts. You must do what you can of good, even by encouraging others, such as uncles, maternal uncles, or older brothers, to advise him and approach him with what helps him to abandon riba (usury or interest).
