A mosque in which sorcery and magic are practiced: Is it permissible for the owner of the mosque to sell the land?

Question:
He says: Honorable Shaykh, may Allah grant you success. A man in the West bought a piece of land and built a mosque on it with his own money, then appointed someone to manage this mosque. However, those in charge of it have gone astray, and they are currently practicing sorcery in this mosque. His question is: The man wants to sell the land to build a new mosque that will be managed by the people of the Sunnah. Is it permissible for him to sell it?

Answer:
He should expel them. He is the one who appointed them, so he should expel them and bring in others who are upright in their creed and religion. The mosque is the one he built, and he is the one who established them in it. If it has become corrupt, he should expel them and remove them. It is not their property. He should expel them from his mosque and place in their stead those who are sound in their creed. Yes. As for selling it, it requires consideration by the judge or the responsible authority. Yes.
