A man worked in a haraam field (dealing in hashish) and made a lot of money and had children. He owns cars, farms and land, all of it from haraam money. He wants to repent – what should he do with his wife, wealth, cars and farms?.
He should get rid of the haraam wealth by spending it in charitable ways. With regard to his wife and children, he need not worry about them.
And Allaah is the Source of strength.
