Riba al Diyun

English: usury of debt

Definition: Also known as usury of delay (riba al nasia).

The usury of debt was an established practice amongst Arabs during the pre-Islamic period. It can occur as an excess increment on top of the principal, which is incorporated as an obligatory condition of the giving of a loan.

Alternatively, an excess amount is imposed on top of the principal if the borrower fails to repay on the due date. More time is permitted for repayment in return for an additional amount. If the borrower fails to pay again, a further excess amount is imposed, etc.
