What does Riba refer to in the context of Sharia law?

In the context of Sharia law, Riba specifically refers to unlawful gain, which is most commonly understood as interest. This concept is considered prohibited within Islamic finance because it is seen as exploitative. Riba is viewed as earning money from money itself without the provision of a good or service, and it contradicts the principles of fairness and risk-sharing emphasized in Sharia law. Traditional Islamic finance promotes profit-and-loss sharing models instead of charging interest, aiming to establish just financial practices that benefit all parties involved.

The other options either describe principles of fairness or financial arrangements that align with Islamic finance, but do not capture the essence of Riba. Fair trade practices, for instance, focus on equitable trading relationships, while interest-free lending agreements align with Islamic finance principles but do not define Riba itself. Legal fees for contract enforcement are related to the enforcement of agreements but are unrelated to the issue of interest as defined in Sharia law. Thus, understanding Riba as unlawful gain or interest is fundamental to grasping the restrictions and offerings of Islamic financial systems.
