He—may Allah have mercy on him—was asked:
“A mosque is an old building with an upper storey. No one has lived in or benefited from that storey because it is dilapidated. Its weight is damaging the mosque and causing it to deteriorate, and the mosque has no funds for repairs. Is it permissible to dismantle the upper storey, or should the mosque be closed?”
He replied:
“If dismantling the upper storey serves the mosque’s interests, it should be dismantled, and the salvaged materials should be used for the mosque’s benefit. If possible, they should be used to purchase property to be endowed for the mosque, or to fund repairs to the mosque or its endowed property.”
He was asked:
“A man leased endowed land and built upon it as he wished. He then endowed that building, stipulating that the rent for the endowed land be paid from the income of the endowment he had established upon it. The judge ruled that the endowment was valid under the conditions stated in its deed. Is it permissible to revoke it or not?
“If, after the endowment has been legally established, its founder wishes to revoke it in order to include others through a second endowment, is that permissible?”
He replied:
“Once the judge has ruled that the endowment is valid, it may not be altered, nor may its conditions be changed.”
