Kitab At-Tauhid

Kitab At-Tauhid is one of the best books on the subject of Tawheed (Tauheed, Tawhid - Monotheism) and ranks high in authenticity. In this book, all the relevant verses of the Qur'an have been discussed reasonably, rationally, and sincerely. The essence of the Qur'an and Sunnah is placed in a very simple manner in this book. 

Kitab At-Tawhid (The Book of Monotheism) by Shaykh Muhammad ibn Abd al-Wahhab is a landmark work in Islamic creed (Aqidah), laying bare the true meaning of Tawheed (monotheism) according to Qur’an and Sunnah. It systematically addresses what Tawheed is, its essential components, what negates it, and the implications of associating partners with Allah. This book discusses, with clarity and scriptural evidence, the rights Allah has upon His servants — that they worship Him alone, with sincere devotion, untainted by shirk, innovation, or false beliefs.

The book is highly respected among Ahlus Sunnah for its authenticity and detail. It cites many verses of the Qur’an, authentic hadith, and opinions of early scholars to define the different categories of Tawheed: Tawheed Al-Rububiyyah (Oneness of Lordship), Tawheed Al-Uluhiyyah (Oneness of Worship), Tawheed Al-Asma wa Sifat (Names & Attributes). It warns against shirk (major & minor), giving false partners, innovation (bidʿah), extremes (ghuluw), and complacency.

More than just theological theory, Kitab At-Tawhid also shows practical consequences: how true Tawheed shapes one’s worship, behaviour, and worldview; how weak or mixed belief leads to spiritual error; and how a Muslim can preserve his creed in daily life. Its style is firm yet straightforward, intended for both new learners and those revisiting foundational beliefs. Hardbound, well-structured, and supported by evidence, this work remains essential in the study of Islamic monotheism and belief.
