Question
A person was among the worst of people and all his money was earned from forbidden means such as gambling and usury. Then he repented afterward, so what should he do with the money earned from gambling, usury, and other forbidden sources?
Answer
I say, and with God's guidance: He must give away all the unlawful money he has earned; because it is impure and it is not permissible to benefit from it, and God knows best.
