Is a woman obligated to pay off the debt of her deceased father, which consists of iron ingots that a man claims he lent to her father twenty years ago, valued at $20, knowing that the man has no proof and the family is unaware of this debt, and that the man did not deal in this type of commodity? And should the payment be in commodity or cash, and at the current or old price?

A person's claim of debt against a deceased individual is not accepted without evidence. If there is no evidence, the claimant has no right to demand it, unless the heirs wish to act cautiously for the deceased. If the debt is proven by evidence, it is repaid by returning the equivalent of the borrowed item (such as an iron bar) if it is a fungible item, or by returning its value at the time of repayment if its equivalent is not found or if it is a non-fungible item, unless both parties agree to return the equivalent for non-fungible items.
