The Foundations of the Faith ( Usoul Al-Imân ) , by Sheikh Muhammad Ibn Abd Al-Wahhâb

Certainly, the main reason for the creation of jinns and men remains and remains the worship of Allah, the Unique. He (Allah, the Exalted) says (meaning of the verse) : " I created the jinns and men only to worship me" [Surat Ad-Dariyat ( who scatter) , verse: 56.]

This is why the uniqueness ( Al-Tawhid ) and the authentic dogma from their blessed sources, which are the Qur'an and the Sunnah of the Messenger of Allah are the very goal of the realization of this worship, and the creed fundamental to the construction of this universe. Its loss would generate a depravity of the universe, even its disorganization or even its destruction.

Allah, the Exalted, says (meaning of the verses) : "If there were in the sky and the earth deities other than Allah, both would certainly be in disorder" [ Surat Al-Anbiya' (the prophets) , verse: 22.

He (the Glorious) also says (meaning of the verses) : “Allah who created seven heavens and as many lands. Between them [ His ] command descends , so that you may know that Allah is, verily, Omnipotent and that Allah has embraced all things of [ His ] knowledge [Surat At-Talaq ( Divorce ) , verse: 12] .

It is a book that includes the foundations of faith in the light of the Koran and the Sunnah. These are great principles, inherited from the Messengers, in all clairvoyance, that it is possible for any mature person to understand in a short period of time.
