Is it permissible to cancel an endowment to avert harm?

Question:
A person wanted to build a mosque under his house and endow it. The practice in this country is that the state controls the mosques, and it may appoint an imam or a mu'adhdhin from among the innovators, or one who has fallen into major shirk (associating partners with Allah). The question is: If this happens, is this person allowed to cancel this endowment to avert this harm, such as the imamate of a mushrik (one who associates partners with Allah) or an innovator?

Answer:
First, regarding making the mosque on the lower level and the residence above, there is a distinction here. If he is developing land and building a mosque on the ground floor with a house above it, this is not permissible initially. However, if there is an existing multi-story building and he takes the lower floor, modifies it, repairs it, and turns it into a mosque, then there is nothing wrong with that. This is permissible, and it is a good deed. He is not allowed to cancel the mosque's endowment on account of the imam. He is not responsible for this; it is the responsibility of the one who has authority over appointing imams. He is a doer of good, so . He should keep the mosque and not cancel its endowment for the sake of the imam. The imam may leave after a year, and Allah may bring an imam better than him. The responsibility lies with the one who appointed him, while the endower is judged by his intention, which is for good. Yes.
