Because of its complete consonance with human spiritual and corporeal nature, it provides for and resolves the true needs of humans as opposed to their fancies or desires. Obviously, the nature and make-up of humankind will remain the same as long as humans are human. Regardless of the time, place, and condition people live in, they will retain their nature. Nature sets its path before us, whether we chose to follow it or steer clear of it.
Hence in truth, the underlying meaning of this question is: if humanity follows the path shown by its nature, will it find happiness and attain its natural aspirations? For instance, if a tree keeps to its natural course—for which it is naturally equipped—will it reach the desired destination of its nature? Clearly such questions are self-evident and skepticism is meaningless in this regard. Islam is the path of primordial nature, which is perpetually the true course of humankind.
It does not vary in different conditions. The aspiration of nature—as opposed to sentimental and irrational desires—are the true desires of the human race and the final destination of human nature is the abode and journey’s end of human happiness and beatitude.
This is the enduring (and true) religion; however, most humans do not know.” [^1] Turn towards and accept the religion, which is the religion that is the special divine genesis upon which Allah has created people, with resolution and moderation. There is no change in the creation of Allah—it is immutable. This is the religion that can manage the lives of people.
A short explanation: As it is manifest and tangible to us, the various types of beings in the world of creation each have a specific life or existence and a definite course. In the course of their existence, they pursue a precise destination. Their happiness and bliss is in attaining their journey’s end without being blocked by corruptive and degenerative obstructions.
