Is it permissible for a bank or government to pay the zakat on cash assets on behalf of a client, with his authorization, from a source other than the amount deposited with the bank, within a financial product aimed at increasing savings awareness?

Bank deposits include two types: the current account, which is considered a loan from the customer to the bank, and the investment account, which is considered a Mudarabah (profit-sharing) or a partnership. The conditions for the investment account are that the investment must be permissible, the capital must not be guaranteed, and a known percentage of the profit must be agreed upon. The bank is permitted to pay zakat on behalf of the customer, with their permission, from the investment account but not from the current account.
