A comprehensive belief system must contain both aspects in the right proportion so that human nature may find in it a correspondence with its own desires and potentialities.
On the one hand, the essence of the Divine Being, the connection between the Will of the Creator and the creation, and the nature of the soul are some of the aspects of the Islamic faith that are beyond human comprehension, while on the other hand there are attributes of Allah, such as His existence, His Oneness, His power, His will, His creativity, and His knowledge, that are within the grasp of human thought.
In fact, human reason insists that the Creator must have these attributes, and Islam gives convincing proofs of them.
Similarly, there are teachings in Islam concerning the universe, its origination in the Divine Will, its subservience to Allah's commands, its potentiality to welcome life, its relationship with man and man's relationship with it, and there are teachings concerning life, its varieties and ranks, its connection with the rest of the universe, and with its Originator, and there are teachings also concerning man and his nature, his origin and characteristics, and the purpose of his existence, and a system for his life.
All these teachings are presented in a clearly understood, logical fashion, which appeals to the intellect and to the heart because these teachings are supported by arguments readily accepted by human intuition. Were they created of nothing? Or are they the creators? Or did they create the heavens and the earth? Nay, they have no certainty (Al-Tur 52:35-36). Some people have taken gods from among earthly things or beings or ideas that allegedly can raise the dead?
Had there been in heaven or on earth any gods other than Allah, both would surely go to ruin. So glory be to Allah, the Lord of the Throne, far above all that men may devise by way of definition! He shall not be questioned as to what He does, but they shall be questioned. And yet they choose to worship (imaginary) deities) other than Him? Say, "Bring proof!
This is a reminder by those who are with me, just as it was a reminder (voiced) by those who came before me." Nay, most of them do not know the truth, and so they are turning away (Al-Anbiya 21: 21- 26). Is not He who created the heavens and the earth able to create the like of them? Yes, assuredly! He is the Supreme Creator, the All-Knowing. Indeed, when He desires a thing, His command is "Be" and it is (Ya Sin 36:81-82).
