‘Your Lord Blessed and Exalted says: ‘Oh son of Aadam, devote yourself to My worship and I will fill your heart with richness and your hands with provision. Oh son of Aadam do not become distant from me lest I fill your heart with poverty and your hands with burdens.’
Al Fudayl bin Iyaad (rahimahullaah) said,”The religion of Allaah is the most sincere of it and the most correct of it.” It was said, “O Abu Ali, what is the most sincere of it and the most correct of it?” He said,
If an action is sincere and it is not correct then it will not be accepted, and if it is correct and it is not sincere then it will not be accpted, until it is sincere and correct, and it will be sincere if it is (done) for Allaah, and it will be correct if it is done upon the Sunnah.
