This book, The Religion of Truth, treats these basic and great subjects. We should know that the only way for our salvation in this life and in the hereafter is to know, for sure, our Lord who created us, believe in Him, and worship Him Alone. We should also know our prophet whom Allah had sent to us and to mankind, believe in Him and follow him. We should know the Religion of Truth which our Lord has commanded us to believe in and practice it.

The Life, Teachings and Influence of Muhammad ibn Abdul-Wahhaab: This book is not one with a political agenda. It is meant neither to support nor to critique any contemporary regimes or policies. Indeed, the driving force behind this work is much greater and more important than that. It has to do with, first, the religion of Islam as preached by the Prophet (peace and blessings of Allah be upon him) himself and, second, with the honor and rights of an individual Muslim, Muhammad ibn Abdul-Wahhaab.
