How can financial grievances be returned to their owners after many long years with the change in the value of money, and should they be returned at the same previous value?

The penitent must return rights to their owners, and these rights do not lapse with the passage of time. The restitution should be in the equivalent of what was stolen or usurped, in the currency of the country at the time of the theft or usurpation. Nothing else is required, even if the price fluctuates. Similarly, a borrower is obligated to return the equivalent of what they borrowed, not its value. The principle in repaying debts is based on returning the equivalent, not the value, and this is the view of the majority of scholars.
