Explanation of the four principles and the three fundamentals and the nullifiers of Islam and uncovering the doubts - Abdulrahman Al-Barrak known as (Taleeqin Usul Al-Aqidah for the general public)

These four texts are among the most famous and important works written by the reviver Imam Muhammad bin Abdul Wahhab on the oneness of worship and issues of worship: defining, demonstrating, refuting doubts about it, and clarifying what contradicts it from beliefs, sayings, and actions.
