This book is about what Islamic finance becomes when it stops translating and starts building. For fifty years, Sharīʿa scholars have retrofitted legal opinions onto a financial architecture designed by others. That work was necessary. It is now finished. The architecture itself is being rebuilt by AI, tokenisation, and programmable ownership, and for the first time in a century the Muslim world has the chance to design rather than adapt.

The Islamic Capital Engine sets out that design in full. It moves from the failure of compliance-only finance to the mechanics of debt fragility, from continuous Sharīʿa risk scoring and machine-readable purification to index construction, ETF operations, on-chain waqf, halal DeFi, and the capital strategy the umma will need across the climate transition, the AI economy, and the space frontier. It closes with a blueprint and a ten-year implementation plan.

None of this can be built by scholars alone, or by financiers alone. The jurist must learn the machinery of markets. The professional must learn the substance of the law. This book is written for both, at once.
