Is an increase in the value of installments after their postponement due to financial hardship considered usury (riba)?

Any increase in the debt in exchange for deferment is unlawful Riba. The Islamic Fiqh Council of the Muslim World League has unanimously agreed that a creditor's condition for the debtor to pay a sum of money as a fine for late payment is a void condition and usury of Jahiliyyah (pre-Islamic era). It should be clarified whether the amount to be paid (2800) is the previous installment or a new installment after the deferment.
