The ruling on borrowing in a local currency and repaying in another currency?

Question:
He says: We have a person we deal with, and we borrow from him in the local currency, and he calculates it in dollars at the time of repayment or at the time of the loan. Usually, it is calculated in dollars at the time of repayment based on the exchange rate at that time. Is this riba (usury or interest)?

Answer:
This is not riba if a person has debts in a specific currency in his liability, and then he agrees with the creditor to pay him in another currency through currency exchange. There is no harm in that, provided two conditions are met. The first condition is that it be at the rate of the day, meaning what it is worth at the time of exchange. The second condition is that they do not separate while anything remains between them. If these two conditions are met, there is no riba in this matter, and praise be to Allah. The Prophet (peace and blessings be upon him) was asked about this, or the Companions used to sell camels in a place for currency, then they would exchange them, selling them for gold, for example, and then exchange them for silver. The Prophet (peace and blessings be upon him) was asked about that, and he said: There is no harm in that if it is at the rate of the day, and they do not separate while anything remains between them. Yes.
