Building a mosque with forbidden money

Question:
He says: Honorable Shaykh, may Allah grant you success. A man obtained a sum of money that is haram (forbidden). Is it permissible for him to build a mosque with it, or something else that Muslims benefit from? And is it permissible to pray inside this mosque built from haram (forbidden) money?

Answer:
If a person collects haram (forbidden) money and then repents to Allah the Exalted, and he has this money collected from haram (forbidden) sources, he should not keep it with him. He should get rid of it by placing it in public projects, like lost money that has no owner, which is placed in public projects such as repairing roads, building public restrooms for people, or repairing parks where neighbors can breathe fresh air. These are public projects that benefit people. As for mosques, no, nothing of this money is to be put in them. Mosques are kept pure from this money. Yes.
