Few concerns are as central to Islam as the search for knowledge (‘ilm). In the Koran God commands the Prophet, by universal Muslim consent the most … - William Chittick

In short, already in the Koran and the Hadith, we find the idea that human beings are created with an innate capacity that allows them to understand things as they really are, but this capacity is clouded by the human environment. The function of the prophets is to “remind” (dhikr) people of what they already know, while the duty of human beings is simply to “remember” (dhikr). Having remembered, they return to the innate capacity from which they have never really become separate.’ If the human spirit knows God and affirms tawhid at the moment of its creation, this is because this spirit is not completely separate from God. In describing the creation of human beings, the Koran says that God molded Adam’s clay with his own two hands, then blew into him of his own spirit. The spirit is God’s breath, and Muslim thinkers were well aware of the implications of the metaphor. Breath is different from the breather; yet it is also the same, since a person without breath is a corpse. The divine breath that animates human clay is not identical with God, nor is it completely different. Human beings are near to God through their spirits, but they are far from him through their bodies made out of clay. The qualities of spirit and body lie at opposite extremes. The spirit is perfect, luminous, alive, rational, aware, intelligent, powerful, desiring, speaking; in short, it possesses all the attributes of God. But the body displays none of these qualities to any perceptible degree. It is merely earth and water, which represent the lowest of created things. When God blows the spirit into clay, this gives rise to the soul or self (nafs), which is an intermediate reality that possesses qualities of both sides. Hence the soul—which is the level of ordinary awareness—lies between light and darkness, perfection and imperfection, intelligence and ignorance, rationality and irrationality, awareness and unawareness, power and weakness. Within the soul, the innate capacity is represented by the luminous qualities of the spirit that are only dimly present. Actualizing the innate capacity in its fullest measure is seen as the goal of human existence. The soul must be transmuted such that its darkness becomes fully infused with spiritual light.

The idea that human beings recognize tawhid innately is often expressed by using the term fitra, which is commonly translated as "primordial nature" or "innate disposition."...The Koran employs the word fitra itself only once, along with the verb form of the word. Here we translate the verb as "bring forth." The Koran is addressing Muhammad and, by extension, every Muslim: "Set thy face to the religion as one with primordial faith—the fitra of God according to which He brought people forth. There is no changing the creation of God. That is the right religion, but most people do not know. [Set thy face to the religion] by turning to Him. And be wary of Him, and perform the salat, and be not one of those who associate others with Him." (30:30-31) Here the Koran connects religion with the nature that human beings were given when they were created. By being human, they have accepted the Trust and entered into the Covenant of Alast. They were taught the names, created in God's form, and singled out for God's vicegerency.

The primacy of thought is made explicit in the first half of the Shahadah, the testimony of faith: “There is no god but God.” This is the one truth upon which all of Islam depends. The tawhid that is expressed here is not contingent upon the facts and events of the world. It is essentially a thought, a logical and coherent statement about the nature of reality. In the Qur’anic view of things, tawhid guides the thinking of all human beings inasmuch as they are true to their innate disposition (fitra). Every messenger from God came with tawhid in order to remind his own people of their humanity. In this way of looking at things, true thought is far more real than the bodily realm, which is nothing but the apparition of thought. This is not to say that the external world has no objective reality, far from it. It is to say that the universe is born from the consciousness, awareness, and thought of the divine and spiritual realms.
