The book consists of several scholarly explanations of the classical work on Tawheed and Shirk. “The Four Rules”, which was written by the Imaam and Mujaddid of the 13th century, Muhammad bin Abdul-Wahhab, may Allah have mercy on him.

It is called “The Four Rules” because it consists of four fundamental issues which on can use to distinguish a believer from a disbeliever and a polytheist from a monotheist. This treatise is considered one of the imaam’s more significant works. Even though it may e more concise than some of his other works, it is just as comprehensive in terms of the information covered and points of benefit discussed.
