1. Is it permissible for the supervisor to postpone receiving the endowment's rent without informing the beneficiaries, and what should the beneficiary do in this situation? 2. Is it permissible for the supervisor to delegate another to perform all supervisory duties on his behalf?

The role of the supervisor (nazir) is to collect the rent of the endowment (waqf), and he is not permitted to postpone collection except with the permission of the beneficiaries, because the usufruct of the waqf belongs to those for whom it was endowed. If the supervisor continues to postpone collection, the beneficiaries may refer the matter to the competent authorities. The supervisor may appoint another person to carry out the duties of supervising the waqf in all or some of the actions he is authorized to perform.
