Islamic science came into being from a wedding between the spirit that issued from the Qur'anic revelation and the existing sciences of various civil… - Hossein Nasr

Man, in the traditional sense of the term corresponding to insan in Arabic or homo in Greek and not solely the male, is seen in Islam not as a sinful being to whom the message of Heaven is sent to heal the wound of the original sin, but as a being who still carries his primordial nature (al-fitrah) within himself, although he has forgotten that nature now buried deep under layers of negligence. As the Quran states: “[God] created man in the best of stature (ahsan altaqwim)” (95:4) with an intelligence capable of knowing the One. The message of Islam is addressed to that primordial nature. It is a call for recollection, for the remembrance of a knowledge kneaded into the very substance of our being even before our coming into this world. In a famous verse that defines the relationship between human beings and God, the Quran, in referring to the precosmic existence of man, states, “‘Am I not your Lord?’ They said: ‘Yes, we bear witness’” (7:172). The “they” refers to all the children of Adam, male and female, and the “yes” confirms the affirmation of God’s Oneness by us in our pre-eternal ontological reality. Men and women still bear the echo of this “yes” deep down within their souls, and the call of Islam is precisely to this primordial nature, which uttered the “yes” even before the creation of the heavens and the earth. The call of Islam therefore concerns, above all, the remembrance of a knowledge deeply embedded in our being, the confirmation of a knowledge that saves, hence the soteriological function of knowledge in Islam.

The Quran, like other sacred scriptures, associates knowledge and understanding with the heart, and the blindness of the heart with loss of understanding, as for example when God, after complaining of man’s not learning the appropriate lessons from earlier sacred history, asserts, “For indeed it is not the eyes that grow blind, but it is the hearts, which are within the bosoms, that grow blind” (22:46). This blindness of the heart so characteristic of fallen man is also described by the Quran as a hardening of the heart. “But their hearts were hardened, and the devil made all that they used to do seem fair unto them!” (6:43). Also, ““Woe unto those whose hearts are hardened against remembrance of Allah. Such are in plain error” (39:22). Furthermore, the Quran identifies this hardening of the heart with a veil that God has cast over the heart of those who have turned away from the truth. “We have placed upon their hearts veils, lest they should understand, and in their ears a deafness” (6:25); also, “And We place upon their hearts veils lest they should understand it, and in their ears a deafness” (17:46).

As a matter of fact one of the great services that Islam can render to the modern world, in which the dichotomy between reason and revelation or science and religion has reached such dangerous proportions, is to represent this possibility of the union between revelation and reason as found in the Quran. The source of revelation in Islam is the Archangel Gabriel or the Universal Intellect. Intellect (al-‘aql al-kulli in the language of hadith) and the word ‘aql itself signify etymologically both that which binds or limits the Absolute in the direction of creation and also that which binds man to the truth, to God himself. In the perspective of Islam it is precisely ‘aql which keeps man on the straight path (the sirat al-mustaqim) and prevents him from going astray. That is why so many verses of the Quran equate those who go astray with those who cannot use their intellect (as in the verses wa la ya‘qilun, ‘they do not understand’ or literally ‘use their intellect’—the verb ya‘qilun deriving from the root ‘aqala which is related to ‘aql; or the verse la yafqahun, ‘they understand not’, the verb yafqahun being related to the root faqiha which again means comprehension or knowledge.)
