Machine translationRead the Arabic original
Question:
Honorable Shaykh, may Allah grant you success, he says: Is it permissible to take a fee from a man who used to deal in riba, or from a man whose original wealth came from what is forbidden?
Answer:
If he has lawful wealth and he has forbidden wealth, there is no harm in taking it, on the condition that it is not established that this wealth is from what is forbidden. If it is not established that it is from what is forbidden, and you know that it is from what is forbidden, it is not permissible. But if you do not know, and he has lawful and forbidden wealth, you assume it is from the lawful. The Prophet (peace and blessings be upon him) used to deal with the Jews, and they used to consume riba, but they had permissible wealth and permissible dealings. Yes.
