Bakara 280-281:

•  Eğer borçlu güç durumda ise, rahatlayıncaya kadar ona mühlet verin. Şunu da bilin ki, borcu bağışlamak sizin için daha hayırlıdır. Allah(cc)'a döneceğiniz, sonra herkesin kazancının kendisine eksiksiz geri verileceği ve hiç kimsenin haksızlığa uğratılmayacağı Hesap gününü aklınızdan çıkarmayın.

  This verse empowers an Islamic court of law to compel the creditors to give more time to the debtors for the payment of debts, if they are in such straitened circumstances that they cannot pay back their debts. Under certain circumstances, the court is entitled to write off the debt altogether or a part of it. A Tradition says that a man suffered loss in his business and came heavily under debt. When his case was taken to the Holy Prophet, he made an appeal to the people to help him out of it. Accordingly, the people made monetary contributions, but even then he could not clear all his debts. Then the Holy Prophet addressed the creditors and told them that they would have to be satisfied with whatever was collected for the payment of their debts. The jurists have explained that the house in which a tnan lives, his utensils, clothes and tools of trade can in no case be confiscated. ET
