Is there any suspicion of usury in repaying a loan in Egyptian Pounds instead of Saudi Riyals—at the current exchange rate at the time of repayment—due to the change in the exchange rate between the two currencies?

It is permissible to repay a debt in a currency different from the loan currency if agreed upon on the day of repayment, and at the exchange rate of that day, provided that no debt remains owing by the debtor. However, it is not permissible to stipulate this at the time of contracting the loan, as it would constitute currency exchange without immediate possession (ṣarf bidūn taqābuḍ), which is impermissible.
