The ruling on the refusal of the person appointed by the endower to serve as supervisor to oversee the endowment

Question:
He says: Honorable Shaykh, may Allah grant you success, if a person says, “I have appointed so-and-so as the supervisor,” and then this supervisor refuses to oversee the endowment, what should be done? And is it permissible for him to refuse?

Answer:
Yes, it is permissible for him to refuse. He says, “By Allah, I do not want to be fully occupied with this; I am busy with such-and-such, I have no time, or I am not good at this.” It is permissible for him to refuse. Then the case is referred to the court, which appoints someone else in his place, appointing another supervisor. Yes.
