What is the ruling on demanding the value of the ten meters that the uncle added to his land, knowing that the price per meter has multiplied several times since the initial agreement whose value was not paid, and that the uncle's sons are offering to pay the previously agreed-upon amount despite 12 years having passed without payment and the increase in the land's price?

You owe them five thousand pounds, but due to the change in currency value, you must give the equivalent value in gold at the time of the initial agreement. Your cousins must hasten to repay their father's debt, for a debt remains attached to the deceased's soul until it is settled. The heirs are sinful if they delay repayment when the deceased has left behind sufficient funds to cover his debt, as this constitutes an injustice to the deceased.
