What should I do about my father's debt to his wife, which is in the form of gold jewelry that he borrowed from me? Should I repay the debt at the current price of gold or at its price at the time of borrowing, especially since I did not reside in the house that was built with this money?

If the enquirer's heart is assured of the truthfulness of his stepmother's claim, and his sisters testify to their father's bequest, then it is obligatory to fulfill this debt to her from the father's estate before its distribution, because it is a debt related to his (the father's) liability, and not the enquirer's. If the father did not leave any money, then the heirs are not obligated to pay the debt. Nevertheless, the enquirer is advised to pay the debt on behalf of his father from his own account if the father did not have enough to pay his debt and the enquirer is able to do so; for this is an act of piety and benevolence towards his father after his death. The Prophet, peace and blessings be upon him, said: "And fulfilling their covenants" is among the acts of righteousness towards one's parents after their death. The debt should be paid at the price of gold on the day of payment or by its weight in gold.
