Author Biography and Historical Context

Wahbah Mustafa az-Zuhayli was born in 1932 CE in Dir Atiyyah, a town in the Qalamoun region of Syria. He pursued a comprehensive traditional Islamic education alongside a modern academic formation, studying at al-Azhar University in Cairo, where he received his doctorate in Islamic law, and subsequently completing legal studies at Cairo University's Faculty of Law. This dual formation — simultaneously rooted in traditional Islamic learning and trained in modern academic and legal methodology — shaped his distinctive scholarly approach.

Az-Zuhayli spent most of his career as a professor at the University of Damascus, where he became the head of Islamic jurisprudence and its schools in the Faculty of Shariah and Law. Over his long career he produced a body of work remarkable for its breadth and accessibility. His magnum opus, Al-Fiqh al-Islami wa Adillatuh, a comprehensive encyclopedia of Islamic law in multiple volumes organized by topic and covering all four major Sunni schools as well as Ja'fari Shi'a law, became the standard modern reference work for comparative Islamic jurisprudence.

The Al-Wajiz fi Usul al-Fiqh was written as an introductory text — the "wajiz" (brief/accessible) in contrast to the longer treatments available in the literature. Az-Zuhayli recognized that despite the existence of both classical usul texts and modern scholarly works on legal theory, there was a need for a pedagogically effective introduction that could introduce students to the discipline without overwhelming them. The work reflects his experience as a teacher who understood what students needed in order to grasp the essentials of Islamic legal theory.

Az-Zuhayli worked in an era of intense discussion about the relationship between classical Islamic law and modern legal systems. Syria and other Arab states had adopted legal codes influenced by European models, and Muslim scholars were grappling with how to relate these modern institutions to the Islamic legal tradition. This context gave questions of usul al-fiqh — the theoretical foundations of Islamic law — a practical urgency beyond their traditional scholarly interest. Understanding the methodology of Islamic law was necessary for thinking seriously about Islamic legal reform and the application of Islamic principles in contemporary contexts. Az-Zuhayli died in 2015 CE.
