Is it permissible for those in charge of a charitable school to take a percentage of the donations as a salary?

Question:
The questioner says: A man is the supervisor of a charitable school, and the money of the donors comes to him. Is it permissible for him to set a salary for himself? And is it permissible for him to invest the money and take its profit?

Answer:
Neither of the two matters is permissible. He may not take anything for himself, because this is for the school and the students. It is not permissible for him to invest it and take its profits. If he invests it in a permissible investment, its profits belong to the school; they belong to the school, not to him. He is merely a doer of good and does not take anything for himself, neither from the donations nor from their profits if he invests them. However, if one of the benefactors gives him something and says, "This is for you in return for your work," there is no harm. But if they pay the donations to the school, it is to be spent on the school, and he does not take anything from it. Yes.
