If a person borrows gold from another and the lender agrees that the borrower returns it in gold and in its original weight, how is it to be calculated? Is it to be calculated according to its weight at the time it was borrowed or the time it is returned?
The principle is that the gold must be returned as gold and in its original weight. If the lender accepts to take the value of the gold, then it is to be calculated according to its value at the time it is returned and not the time it was loaned. This is because the principle is that gold must be paid back as gold.
Allah Almighty knows best
