When thy Lord said to the Angels, “Verily I am about to place one in my stead on earth”, they said, “Wilt Thou place there one who will do ill and shed blood, when we celebrate Thy praise and extol Thy holiness?” God said, “Verily I know what ye know not!” And He taught Adam the names of all things, and then set them before the Angels, and said, “Tell me the names of these if ye are endowed with wisdom”. They said, “Praise be to Thee! We have no knowledge but what Thou hast given us to know. Thou art the Knowing, the Wise”. He said, “O Adam, inform them of the names”. And when he had informed them of the names, God said, “Did I not say to you that I know the hidden things of the Heavens and of the earth, and that I know what ye bring to light and what ye hide?” (2: 30-33).
The point of these verses is that man is endowed with the faculty of naming things, that is to say, forming concepts of them, and forming concepts of them is capturing them. Thus the character of man’s knowledge is conceptual, and it is with the weapon of this conceptual knowledge that man approaches the observable aspect of Reality. The one noteworthy feature of the Qur’an is the emphasis that it lays on this observable aspect of Reality. Let me quote here a few verses:
Assuredly, in the creation of the Heavens and of the earth; and in the alternation of night and day; and in the ships which pass through the sea with what is useful to man; and in the rain which God sendeth down from Heaven, giving life to the earth after its death, and scattering over it all kinds of cattle; and in the change of the winds, and in the clouds that are made to do service between the Heavens and the earth– are signs for those who “understand” (2:164).And it is He Who hath ordained for you that ye may be guided thereby in the darkness of the land and of the sea! Clear have We made Our signs to “men of knowledge”. And it is He Who hath created you of one breath, and hath provided you an abode and resting place (in the womb). Clear have We made Our signs for “men of insight”! And it is He Who sendeth down rain from Heaven: and We bring forth by it the buds of all the plants and from them bring We forth the green foliage, and the close-growing grain, and palm trees with sheaths of clustering dates, and gardens of grapes, and the olive, and the pomegranate, like and unlike. Look you on their fruits when they ripen. Truly herein are signs unto people who believe (6: 97-99).Hast thou not seen how thy Lord lengthens out the shadow? Had He pleased He had made it motionless. But We made the sun to be its guide; then draw it in unto Us with easy in drawing (25: 45-46).Can they not look up to the clouds, how they are created; and to the Heaven how it is upraised; and to the mountains how they are rooted, and to the earth how it is outspread? (88: 17-20).And among His signs are the creation of the Heavens and of the earth, and your variety of tongues and colours. Herein truly are signs for all men (30: 22).
No doubt, the immediate purpose of the Qur’an in this reflective observation of Nature is to awaken in man the consciousness of that of which Nature is regarded a symbol. But the point to note is the general empirical attitude of the Qur’an which engendered in its followers a feeling of reverence for the actual and ultimately made them the founders of modern science. It was a great point to awaken the empirical spirit in an age which renounced the visible as of no value in men’s search after God. According to the Qur’an, as we have seen before, the universe has a serious end. Its shifting actualities force our being into fresh formations. The intellectual effort to overcome the obstruction offered by it, besides enriching and amplifying our life, sharpens our insight, and thus prepares us for a more masterful insertion into subtler aspects of human experience. It is our reflective contact with the temporal flux of things which trains us for an intellectual vision of the non-temporal. Reality lives in its own appearances; and such a being as man, who has to maintain his life in an obstructing environment, cannot afford to ignore the visible. The Qur’an opens our eyes to the great fact of change, through the appreciation and control of which alone it is possible to build a durable civilization.
