It being controversy that Islamic banks still have usury because it is proven that there is a fine if they are late in paying instalments, which is the practice of jahiliya usury.
Actually, the context of jahiliya usury used to be that if the borrower could not pay the debt according to the agreed time and then asked for a deferral of payment, the time delay was granted but he needed to pay additional money.
And need to understand that the additional money requested to replace the provision of the suspension period goes into the income of the person giving the debt and he can use it for consumption activities.
Whereas in Islamic Financial Institutions , the fines given are not included in the income post and the fine is given specifically to customers who can afford it but delay payments.
According to the hadith of the Prophet which states:
'Delay in payment by debtors who can afford it is an injustice'
But how come in practice many are unable to pay but still get fines? The answer is, because the customer does not want or may not show the real conditions which can indicate that he is in trouble.
Please note, in Islamic banks there is also such a thing as restructuring. There are three types of restructuring schemes, namely: Rescheduling, Reconditioning, and Restructuring.
Customers who in a bad financial condition but have a commitment and good faith, then just submit the financing restructuring process, then the bank will not impose a fine.
According to QS. Al-Baqarah 280:
'And if the debtor is in trouble, then give him toughness until he is free.'
