The contributions of Bernard Weiss to the study of the principles of jurisprudence (uṣūl al-fiqh) are recognized in a series of contributions on Islamic legal theory. These thirteen chapters study a range of Islamic texts and employ contemporary legal, religious, and hermeneutical theory to study the methodology of Islamic law. Contributors include: Peter Sluglett, Ahmed El Shamsy, Éric Chaumont, A. Kevin Reinhart, Mohammad Fadel, Jonathan Brockopp, Christian Lange, Raquel M. Ukeles, Paul Powers, Robert Gleave, Wolfhart Heinrichs, Joseph Lowry, Rudolph Peters, Frank E. Vogel

Focuses on a Muslim legal science known in Arabic as usul al-fiqh. Whereas the kindred science of fiqh is concerned with the articulation of actual rules of law, this science attempts to elaborate the theoretical and methodological foundations of the law. It outlines the features of Muslim juristic thought.

This book explores the relationship between custom and Islamic law and seeks to uncover the role of custom in the construction of legal rulings. On a deeper level, however, it deals with the perennial problem of change and continuity in the Islamic legal tradition (or any tradition for that matter).

This book deals with the theory and practice of Islamic law in both the formative classic and modern periods and over a wide range of societies. The book also focuses on the role of Ijtihad in both Sunni and Shi'i fiqh and in collections of fatwa

“The world today has become one large village. Muslims and non-Muslims live side by side and have to learn about one another, share commonalities and respect differences. At this time more than one and a half billion Muslims live in this village. Some of them are pious Muslims, trying to live in accordance with Islamic rules, whereas others do not while believing that these rules come from God (the Qur’an), from interpretations of His Messenger (the Sunnah) or the consensus of Muslim jurists (ijmâ‘), and are at least rules derived via analogy (qiyâs) from the main sources of Islam. Most Muslims think along these lines and agree with the above. The reader should remember that Muslim individuals should live according to Islamic rules in private, but no individual is responsible for implementing Islamic law. In any event, the need to learn the facts about Islamic law is necessary for Muslims as well as for non-Muslims if they live in the same society with Muslims, at least in the sense of general information. In any event, the need to learn the facts about Islamic law is necessary for Muslims as well as for non-Muslims if they live in the same society with Muslims, at least in the sense of general information. We should keep in mind here that only sovereign Muslim states/governments have the legal authority to implement Islamic law. An individual Muslim has no legal authority or power to implement Islamic law. The law of Islam certainly does not say that every Muslim is obliged to implement Islamic law. It matters not how efficient and popular that individual may be as a brave warrior or a meticulous planner of unlawful and immoral schemes of hatred, terror and destruction. Only people who are properly qualified and trained, and hold a license from Muslim governmental authorities, have the authority to issue fatwâs. Not every Muslim individual qualifies as a Muftî (a jurist-consult or scholar of law who has been given a license to issue fatwâs.). For this reason Bediuzzaman says: “And we know that the fundamental aims of the Qur’an and its essential elements are fourfold: divine unity (al-tawhîd), prophethood (al-nubuwwah), the resurrection of the dead (al-hashr), and justice (al-ʿadalah). Al-Adâlah means law. He adds in another treatise: “Let our ulul-amr (satesmen and political authorities) think over implementing these rules”. This book is divided into eight chapters. Chapter I.Because of the many misunderstandings that arise, some terms related to Islamic Law, such as Sharî‛ah, fiqh, qânûn, ‘urf, Islamic Law, and Muhammadan Law are explained. Chapter II.Here, in this chapter dedicated to references on Islamic Law, the real added value of this book is found. Chapter III. This chapter looks at four periods of Islamic Law: the period of the Prophet Muhammad, the period of the Companions, the period of the Tabi‘în, and an introduction to the period of Mujtahidîn. Chapter IV. We will provide detailed information here on the different law schools and theological divisions. Chapter V. This chapter will be devoted to a period of Islamic law that has been neglected in both old and new books and articles, i.e. the period of Islamic Law after the Turks converted to Islam (960-1926). Chapter VI. This chapter will focus also on three main subjects: Anglo-Muhammadan law (Indo-Muslim law), Syariah or Islamic Law in Southeast Asia, and Islamic Law in contemporary Muslim states like Egypt, Pakistan, Morocco, Indonesia and Jordan. Chapter VII. We will explain the system and methodology of Islamic Law in this chapter. Chapter VIII. We will give some brief information here on the implementation of Islamic Law, its future; some encyclopedical works on Islamic law, and new institutions of Islamic fiqh.”

Wael B. Hallaq has already established himself as one of the most eminent scholars in the field of Islamic law. In this book, first published in 1997, the author traces the history of Islamic legal theory from its early beginnings until the modern period. Initially, he focuses on the early formation of this theory, analysing its central themes and examining the developments which gave rise to a variety of doctrines. He concludes with a discussion of modern thinking about the theoretical foundations and methodology of Islamic law. In organisation, approach to the subject and critical apparatus, the book will be an essential tool for the understanding of Islamic legal theory in particular and Islamic law in general. This, in combination with an accessibility of language and style, will guarantee a readership among students and scholars and anyone interested in Islam and its evolution.

This book offers the first sustained jurisprudential inquiry into Islamic natural law theory. It introduces readers to competing theories of Islamic natural law theory based on close readings of Islamic legal sources from as early as the 9th and 10th centuries CE. In popular debates about Islamic law, modern Muslims perpetuate an image of Islamic law as legislated by God, to whom the devout are bound to obey. Reason alone cannot obligate obedience; at most it can confirm or corroborate what is established by source texts endowed with divine authority. This book shows, however, that premodern Sunni Muslim jurists were not so resolute. Instead, they asked whether and how reason alone can be the basis for asserting the good and the bad, thereby justifying obligations and prohibitions under Shari'a. They theorized about the authority of reason amidst competing theologies of God. For premodern Sunni Muslim jurists, nature became the link between the divine will and human reason. Nature is the product of God's purposeful creation for the benefit of humanity. Since nature is created by God and thereby reflects His goodness, nature is fused with both fact and value. Consequently, as a divinely created good, nature can be investigated to reach both empirical and normative conclusions about the good and bad. They disagreed, however, whether nature's goodness is contingent upon a theology of God's justice or God's potentially contingent grace upon humanity, thus contributing to different theories of natural law. By recasting the Islamic legal tradition in terms of legal philosophy, the book sheds substantial light on an uncharted tradition of natural law theory and offers critical insights into contemporary global debates about Islamic law and reform.
