For Muslims the Islamic Shari'ah, or Divine Law, is the concrete embodiment of the Divine Will as elaborated in the Quran for the followers of Islam;… - Hossein Nasr

The fullest meaning of the intellect and its universal function is to be found in the ma‘rifah or gnosis, which lies at the heart of the Islamic revelation and which is crystallized in the esoteric dimension of Islam identified for the most part with Sufism. There are verses of the Quran and hadiths of the Prophet that allude to the heart as the seat of intelligence and knowledge. The heart is the instrument of true knowledge, as its affliction is the cause of ignorance and forgetfulness. That is why the message of the revelation addresses the heart more than the mind as the following verses of the Quran reveal: O men, now there has come to you an admonition from your Lord and a healing for what is in the breasts (namely the heart) and a guidance, and a mercy to the believers. Surah (10:57) (Arberry translation)

Through the downward flow of the river of time and the multiple refractions and reflections of Reality upon the myriad mirrors of both macrocosmic and microcosmic manifestation, knowledge has become separated from being and the bliss or ecstasy which characterizes the union of knowledge and being. Knowledge has become nearly completely externalized and desacralized, especially among those segments of the human race which have become transformed by the process of modernization, and that bliss which is the fruit of union with the One and an aspect of the perfume of the sacred has become well-nigh unattainable and beyond the grasp of the vast majority of those who walk upon the earth. But the root and essence of knowledge continues to be inseparable from the sacred for the very substance of knowledge is the knowledge of that reality which is the Supreme Substance, the Sacred as such, compared to which all levels of existence and all forms of the manifold are but accidents.

There is something "God-like" in man as attested to by the Quranic statement, (Pickthall translation): "I have made him and have breathed into him my spirit" (Quran 15:29), and by the tradition, "God created Adam upon His own form." God created Adam, the prototype of man, upon "His own form," i.e., as a mirror reflecting in a central and conscious manner His Names and Qualities. There is, therefore, something of a "sacred nature" (malakut'i) in man; and it is in the light of this profound nature in man that Islam envisages him. This belief is not, however, in any way anthropomorphic, for the Divine Essence (al-Dhat) remains absolutely transcendent and no religion has emphasized the transcendent aspect of God more than Islam. The Islamic concept of man as a theomorphic being is not an anthropomorphism. It does not make God into man. Rather, the Islamic revelation conceives of man as this theomorphic being and addresses itself to that something in man which is in the "form of the Divine." That something is first of all an intelligence that can discern between the true and the false or the real and the illusory and is naturally led to Unity or tawhid.
