This document provides an overview of Islamic finance by differentiating it from the theoretical Islamic economy. It explains that the Islamic economy model prohibits interest and encourages social justice, but remains theoretical as no country fully implements it. Islamic finance, on the other hand, applies Islamic principles like prohibiting interest (riba) to individual transactions within the Western economic model. It works within current systems to develop Sharia-compliant products. The document then discusses how Islamic institutions must adhere to Sharia law as defined by the Quran and hadith. It explains that interest is forbidden in Islam due to unfair risk allocation. Finally, it introduces Islamic capital markets, using Saudi Arabia as an example.
