Introduction

Dr. Abū Ameenah Bilal Philips (b. 1947) is a Jamaican-Canadian Islamic scholar who embraced Islam in the early 1970s and went on to pursue formal Islamic education in Saudi Arabia, completing a Bachelor's degree in Islamic Studies from the Islamic University of Madinah and a Master's degree and doctorate in Islamic theology from the University of Wales. His academic training situates him in the tradition of classical Ahl al-Sunnah scholarship, with a particular emphasis on the Atharī approach to creedal questions that characterizes the curriculum of the Islamic University of Madinah. Over subsequent decades he became one of the most widely read English-language authors on Islamic theology, authored dozens of titles on ʿaqīdah, tafsīr, and Islamic jurisprudence, and founded the Islamic Online University to provide accessible Islamic higher education to an international student body. Fundamentals of tawhid represents his most sustained and systematic treatment of the topic most central to Islamic belief.

The book is organized around the classical threefold categorization of tawḥīd as developed by Muslim scholars: Tawḥīd al-Rubūbiyyah, the affirmation of Allah's sole lordship over all creation; Tawḥīd al-Asmāʾ wa-l-Ṣifāt, the affirmation of Allah's names and attributes as they appear in revelation without distortion, negation, comparison, or modality; and Tawḥīd al-Ulūhiyyah, the exclusive dedication of all acts of worship to Allah alone. Dr. Philips surveys each category, explains its Quranic and Sunnaic basis, and then examines the violations of each category that constitute shirk in its various forms. The work proceeds to examine specific practices that classical scholars have identified as incompatible with pure monotheism, including certain forms of tawassul, saint veneration, and popular superstitions, discussing them with reference to primary textual sources and the verdicts of recognized classical scholars. The writing style is deliberately accessible, aimed at English-speaking readers encountering these topics formally for the first time.

Fundamentals of tawhid has become one of the most widely circulated English introductions to Islamic monotheism since its first publication. It filled a genuine gap in English-language Islamic literature at a time when systematic treatments of ʿaqīdah accessible to Western Muslim audiences were scarce, and it has served as a gateway text for thousands of readers seeking a grounded understanding of the theological foundations of Islam. The book's framework of the three categories of tawḥīd, drawn from classical scholarship, gave many English-speaking readers their first exposure to a conceptual vocabulary that had long been standard in Arabic-language creedal literature. It is frequently assigned in Islamic studies courses and used in mosque education programs across North America, Europe, and other regions with substantial English-speaking Muslim communities. Its influence on popular Anglophone Islamic theological discourse has been considerable.

Readers approaching this book should understand that it is written from a clearly Atharī perspective on creedal questions, particularly regarding the divine attributes, and that its assessments of certain popular religious practices reflect the positions of scholars in that tradition. This does not diminish the book's value as an introduction but does mean that students who encounter differing views within the broader Sunni tradition, including positions held by Ashʿarī and Māturīdī scholars on specific questions, will benefit from supplementing their reading with works representing those schools as well. The book's greatest strength lies in its clarity of structure and its rootedness in Quranic and ḥadīth evidence, which makes it a reliable and manageable starting point for the study of Islamic ʿaqīdah. Readers who complete it will possess a clear map of the categories of monotheism and a working vocabulary for engaging more advanced classical texts on the subject.
