What is the ruling on taking an advance salary from the bank in exchange for a fixed fee?

This transaction is a loan from the bank to the employee, repaid from their salary. The transaction is permissible if the added fees are equivalent to the actual administrative costs incurred by the bank. It is stipulated that the added amount must not be tied to the value of the loan and its value must genuinely correspond to the bank's cost; otherwise, it is considered prohibited usurious increase. Allah Almighty says: (O you who have believed, fear Allah and give up what remains [due to you] of interest, if you should be believers).
