How do the heirs deal with their deceased father’s forbidden wealth?

Question:
In his final question, this questioner says: A man acquired wealth from a forbidden source, then traded with this wealth until he made a large profit, and then this man died. He had righteous children. What is the ruling on the inheritance they received from their father from this forbidden wealth? Some of the sons were scrupulous about taking it, so they referred the matter to us. May Allah reward you.

Answer:
If they are certain that it is all from a forbidden source, then it and its profits are forbidden. They must place it in one of the public projects and dispose of it, and it is not permissible for them to consume it because they know it is forbidden. However, if the matter is one of conjecture and doubt, and it has not been established for them that it is forbidden, then the default is permissibility, praise be to Allah. Yes.

The presenter:
May Allah reward you with good.
