Workers who take water from the mosque’s cooler and the mosque’s private restrooms to wash cars

Question:
He says: Honorable Shaykh, may Allah grant you success. A discussion took place between me and the mosque imam because there are workers who take water from the cooler and the mosque’s private restrooms to wash cars. I told him that this is not permissible because the water is an endowment. Is this statement correct?

Answer:
Yes, this statement is correct. They should not mess with the mosque’s water, taking the coolers and leaving people to drink warm water instead of cold. This is not obligatory; rather, they must be prevented from doing this. They should be prevented from washing the cars. They should leave their work now and go wash the cars. They must be prevented from this, because they should not be washing the cars; the workers should be working. Yes.
