How can a financial trust (300 Egyptian Pounds) be repaid after 22 years, following the death of its owner? Should it be repaid at its value at the time it was received, or at its current value? And how is its current value calculated to deliver it to the owner's heirs?

The duty was to return the money to the sender due to the inability to ascertain the recipient's address. Given the long delay in returning the money, repentance is due for this shortcoming, and the money must be returned to the heirs of the deceased, in the amount that was received. However, if the money was invested, it must be returned along with its profits. There is a disagreement among jurists regarding whether the profit follows the capital or the effort, and the operative fatwa is that the profit follows the capital.
