Is the transaction offered by the public institution for installment payments, which involves paying 30% of the car's value upfront and deferring the remaining amount over five years with a 5% annual charge on the car's price, permissible under Sharia law?

It is permissible for the bank to sell the car to the employee in installments if the bank owns the car and takes possession of it from the company before selling it, and provided that the contract does not stipulate installment interest separate from the price, and that the contract does not include a penalty clause for late payment. However, if the bank's role is merely financing, by paying the price in cash and collecting it in installments with an increase, then this is usury (riba).
