This book is the first comprehensive treatment of Islamic contract law in the English language, and it serves as both a reference work and an authoritative statement of the law and the Fiqh underlying it. The book's structure draws from the tradition of western contract law books to enable non-expert readers to easily navigate its structure, sources and application. It covers the complete spectrum of Islamic contract regulation, and includes chapters on the formation of contracts, the sources of Islamic contract law, the role of intention, legal capacity, the importance of the subject matter, as well as the prohibited elements of contracts. Further chapters discuss validity and defects, contractual terms, bilateral agreements, equity-based partnership contracts, ancillary and unilateral contracts, termination and damages, and the role of third parties. Finally, a chapter is devoted to the application of Islamic law in contemporary Muslim-majority legal systems
