How should a person advise his father if he is dealing in riba (usury or interest)?

Question : The questioner says: Honorable Shaykh, I have learned that investing in one of the banks is considered riba (usury or interest), and my father has invested in this bank. How should I advise him? I think I will not be able to convince him, because the amount he earned is large, exceeding one million riyals. So what is the way to do this? May Allah reward you with good.

Answer : The way to this is for you to advise him. If you are unable to convince him, take a written advice from the scholars whom your father respects and trusts their opinion. Explain it to him and say to him: "O my father, spend this money in charitable projects. If you are eligible for the reward, the reward is yours. If you are not eligible for it, you have been saved from its sin and its consequences. In my opinion, any rational person who is presented with such an opinion will accept it."
