Is it permissible to take a loan of 200,000 Saudi Riyals from the International Islamic Bank to repay 212,000 Saudi Riyals after four years for a commercial project, and what is the difference between this transaction and usury if it is permissible, and which is better: buying a car in installments through the bank or through a car dealership at a higher price?

If the bank or another entity sells a commodity it owns in known installments, and does not stipulate forbidden conditions such as an increase in case of late payment, then the transaction is valid. However, if it lends an amount with an increase, then it is forbidden usury (riba). The difference between them is that the valid transaction involves the sale of a commodity owned by the seller for a known price, whereas usury is lending money with interest. For the transaction to be sharia-compliant, the bank must genuinely purchase the commodity first, and then sell it to the customer.
