Ruling on delaying payment of bills on which interest is charged
Question

                What is the ruling on paying monthly bills which should be paid by a specific date after this date, knowing that interest will be charged on this amount (and if part of the amount is paid, interest will be charged on the remaining amount) if payment is not made before the specified date?.
Praise be to Allah.The one who 
    has bills to pay should not delay payment if delay will result in penalties, 
    because the penalty in this case is riba (interest, usury). This is the riba 
    of the Jaahiliyyah which is also known as riba al-nasi’ah. The owner of the 
    wealth would say to the debtor: “Either pay the debt or it will be 
    increased.” 
The one who 
    delays payment when he is able to pay is a partner in this riba, and the sin 
    is on both parties. 
The 
    Messenger  (peace and blessings of Allaah be upon him) cursed the one 
    who consumes riba and the one who pays it. Narrated by Muslim (1597). 
But if he 
    delays payment and he did not know about this situation, or he delayed it 
    because of pressing circumstances, then the sin is on the company that 
    imposes this penalty of riba. 
These 
    companies and institutions should give up charging these riba penalties; 
    they could warn people and withhold services from them instead of charging 
    these riba penalties. 
And Allaah knows 
    best.
