This research paper explores the core principles and operational mechanisms of Islamic banking and finance. It delves into the prohibition of interest (riba), profit-sharing models, and ethical considerations that distinguish Islamic finance from conventional banking. The paper further examines the key products and services offered, such as Murabaha, Mudaraba, and Sukuk, and analyzes their practical applications in the modern financial landscape. Furthermore, the study will briefly touch upon the governance framework and regulatory aspects, including Sharia compliance, shaping the sector's integrity and development.
