Introduction

Muhammad ibn Abd al-Wahhab ibn Sulayman at-Tamimi was born in 1115 AH (1703 CE) in the Najd region of the Arabian Peninsula, in the town of al-Uyaynah. He studied the Islamic sciences in Mecca and Medina, and traveled to Basra and other centers of learning, before returning to Najd with a reformist mission focused on what he identified as widespread departures from pure tawhid among the Muslim populations of the region — including the veneration of graves, the seeking of intercession from the deceased, and various practices he argued had no basis in the Quran, the authenticated Sunnah, or the practice of the Companions. His Kitab at-Tawhid (The Book of Monotheism), composed in a direct and accessible style, became the foundational text of his teaching and has been one of the most widely printed and distributed Arabic works in Islamic history over the past two centuries.

The Kitab at-Tawhid is organized into sixty-seven chapters, each centered on a specific aspect of tawhid al-uluhiyyah (the oneness of Allah in worship) or on one of its violations. The structure is deliberately textual: for each chapter, Ibn Abd al-Wahhab cites the relevant Qur'anic verses and authenticated hadiths, sometimes with minimal commentary, sometimes with brief explanatory notes drawing on the exegetical tradition, and concludes each chapter with a list of derived legal and theological lessons. This format was chosen to make clear that every position in the book rests on revealed evidence rather than on the author's personal opinion. The methodology reflects the broader Athari approach to theology — that the texts of revelation, understood in accordance with the understanding of the Salaf, are the primary and sufficient basis for doctrinal positions.

A central distinction in the book is between the three categories of tawhid as articulated in the Athari tradition: tawhid ar-rububiyyah (acknowledging Allah alone as the Lord and Creator), tawhid al-asma was-sifat (affirming the names and attributes of Allah as they appear in revelation without distortion or denial), and tawhid al-uluhiyyah or al-ibadah (directing all acts of worship exclusively to Allah). Ibn Abd al-Wahhab's primary focus is on the third category, which he argues was widely neglected or violated in the practices of his contemporaries. The early chapters address the obligation to worship Allah alone and the promise of salvation attached to it; the middle chapters catalog specific violations — major shirk through calling on other than Allah, minor shirk through ostentation (riya), and innovations that open the door to shirk; and the later chapters address subtler matters such as the rulings on omens, magic, and seeking blessings from created things.

The reception of the Kitab at-Tawhid among the scholars of Ahl us-Sunnah has been extensive. The most important classical commentary is Fath al-Majid by Abd ar-Rahman ibn Hasan Aal ash-Shaykh (the author's grandson), supplemented by Taysir al-Aziz al-Hamid by Sulayman ibn Abdullah Aal ash-Shaykh. Scholars of the Permanent Committee for Islamic Research and Fatwa in Saudi Arabia and their predecessors at the Islamic University of Madinah have endorsed the text repeatedly as a reliable expression of Athari aqeedah grounded in the Quran and Sunnah. The book has also been the subject of critical engagement from scholars across the Sunni spectrum who dispute specific methodological choices or contextual judgments; these scholarly debates are part of the living tradition of Islamic theological discourse.

Readers approaching the Kitab at-Tawhid are advised to do so with a commentary, particularly Fath al-Majid, which supplies the contextual information and elaboration that Ibn Abd al-Wahhab's concise format intentionally omits. English translations are available from Darussalam and other publishers; these vary in quality, and consulting more than one rendering alongside the Arabic text is advisable for serious students. The book's real value emerges through careful reading and reflection on each piece of evidence cited — it is a book designed to be studied, not read through quickly, with each chapter prompting self-examination about one's own relationship to the Qur'anic command to worship Allah alone.
