[Text from Imam Muhammad Ibn ‘Abdul-Wahhaab’s "Four Rules Regarding Shirk"]
Know, may Allaah grant you the ability to obey Him, that the Haneefiyyah, the religion of Ibraaheem is that you worship Allaah alone, making the Religion sincere for only Him, as Allaah says:
وَمَا خَلَقْتُ الْجِنَّ وَالْإِنسَ إِلَّا لِيَعْبُدُونِ
“And I did not create the Jinn and mankind except to worship Me.”
[Surah Adh-Dhaariyaat: 56]
So when you come to realize that Allaah created you in order to worship Him, then know that worship is not called worship unless it is accompanied by Tawheed, just as prayer is not called that unless it is accompanied by (ritual) purity. So if Shirk (mixing partners) enters into one’s worship, it ruins it, just like impurity when it enters into the (ritual) purity.
So when you come to realize that Shirk – when mixed into one’s worship – spoils it, invalidates one’s actions, and makes the person who possesses it into one who will reside eternally in the Hellfire, you will know that the most important thing that is binding upon you is to gain knowledge of that, so that perhaps Allaah may absolve you from this trap, which is ascribing partners to Allaah (i.e. Shirk) about which Allaah said:
إِنَّ اللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَاءُ
“Verily, Allaah does not forgive that partners be ascribed to Him in worship, but He forgives what is less than that to whom He wills.” [Surah An-Nisaa: 116]
This can be achieved by knowing Four Rules that Allaah has mentioned in His Book.
