The Ruling on Spending from Forbidden Wealth on Charitable Projects

Question:
The questioner: Honorable Shaykh, is it permissible to do good deeds with forbidden wealth, such as building mosques and hospitals? May Allah reward you with good.

Answer:
The Shaykh: If the owner of the forbidden wealth repents from it, if the owner repents from it, because some people say, "I will take forbidden wealth and spend it on charitable projects," and they will continue with this, no, this is not permissible for you. You must abandon dealing in forbidden wealth. If you abandon it and you are done with it, and you have accumulated wealth that you took and possessed, then you dispose of it by placing it in public projects, because this is like lost wealth that has no owner; it is placed in public projects such as repairing roads, providing water, and the like, or in public restrooms that people need. As for mosques, they are kept pure from this earnings, and mosques are not built from forbidden gains. Indeed, Allah is Pure and does not accept except what is pure. Yes.
