How is a debt from 1968 settled when the debtor died before repaying it, and should the amount be returned as it is, or according to its purchasing power at that time, and what is the ruling on settling the debt with the purchasing power of gold to avoid currency fluctuations?

Scholars have differed on the issue of the change in the value of currency after a debt becomes due. The majority opinion is that the exact same currency must be repaid without increase or decrease. Some, however, have held that the value of the currency at the time the debt became due, or in the case of an excessive change, must be repaid.

The lender is advised to seek reward from Allah and be content with any shortfall. The heirs of the borrower are urged to repay with excellence, citing the Hadith: "Indeed, the best among you are those who are best in repaying."

The preponderant opinion is that of the majority, which states that the debt must be repaid in kind, not by value, as long as the currency is in circulation. This is what achieves stability in transactions.
