اﻟﻘﻮاﻋﺪ اﻷرﺑﻊ — The Four Fundamental Principles Workbook

Importance of Learning and Understanding this Treatise - Shaykh Bin Bāz (rahimahullah)

“These Four Fundamental Principles highlighted by Shaykh al-Islām Muhammad Ibn Abdul Wahhāb are extremely important. 

Whoever understands and comprehends them well, has understood the religion of the polytheists and (also) understood the religion of the Muslims. 

Most of creation do not understand these fundamentals — due to this, affairs have become obscure for them and they worship other than Allah such as graves, the dead, the awliyā’, trees and stones. 

This is all whilst deeming that they are upon something (good) due to their ignorance of the reality of Tawheed and the reality of Shirk.”
