It has been mentioned earlier that faith emerges from the depths of the heart, and in this matter mere abstract knowledge does not suffice. It has been stated in the tradition that any kind of riya’ is polytheism, but this vice, this disastrous atrocity, this hidden cruelty (to one’s own self), and this vicious habit, results in nullifying the good deeds, and in surrender of the realm of the heart to other than God.
The darkness of this vice causes man to leave this world as an unbeliever in God, and the feigned faith that he had assumed proves nothing more than a senseless and empty profession; it is a form without content, a body without soul and a skull without brain; and in no way is acceptable to God.
I accept only those acts that are purely done for My sake.”[^2] Hence, it is clear that if the spiritual acts (of the heart) are not performed with sincerity of the heart, they will neither be the object of attention of the Almighty, nor will He acknowledge them, and they will be credited in the account of that partner-the person, for whose sake they were performed.
Thus the spiritual acts performed for the sake of somebody else, not for God, will surpass the limits of polytheism, and will enter the domain of kufr (infidelity). It may even be said that the performer of such adulterated acts would be treated as one of the munafiqun. As his polytheism is not visible, his hypocrisy also is hidden.
He, the poor fellow, considers himself to be a believer, whereas in reality he is an idolater, and he is condemned to taste the chastisement prescribed for the munafiqun. How pitiable is the plight of one whose good deeds are to terminate in nifaq.
Difference Between Knowledge And Belief Know that faith or belief is something different from the knowledge of God, the Unity of His Being, and His other Attributes--like sifat al-kamaliyyah (the Attributes of Perfection), the Positive Attributes, sifat al-jalaliyyah (the Attributes of Glory), and the Negative Attributes, etc.
