Yet, for the majority of people, because of their continuous preoccupation with material things and their being drowned in the pleasures of the senses, it has become very difficult to return to their God-given, simple, primordial, and untainted nature. That is why Islam, which describes itself as universal, and which believes all people to be equal in religion, has made it possible for such people to find another way to prove the existence of God. It seeks to speak to them and to make God known to them by means of the very path through which they have turned away from their simple, primordial nature.
The Holy Quran instructs the multitude of men in the knowledge of God through different ways. Most of all, it draws their attention to the creation of the world and the order which reigns over it. It invites men to contemplate the "horizons" and "their own souls," for man in his few days of earthly life, no matter what path he chooses or what state he loses himself in, will never step outside the world of creation and the order which reigns over it. His intelligence and power of comprehension cannot overlook the marvelous scenes of heaven and earth which he observes.
This vast world of existence which stretches before our eyes is, as we know, in its parts and as a whole continuously in the process of change and transformation. At each moment it manifests itself in a new and unprecedented form. It becomes actualized under the influences of laws which know no exception. From the farthest galaxies to the smallest particles which form the parts of this world, each part of creation possesses an inward order and runs its course in a most amazing manner under laws which do not admit any exceptions. The world extends its domain of activity from the lowest to the most perfect state and reaches its own goal of perfection.
Above these particular orders stand more universal orders and finally the total cosmic order which brings together the countless parts of the universe and relates the more particular orders with each other, and which in its continuous course accepts no exceptions and permits no breaches.
The order of creation is such that if, for example, it places a man upon the earth, it constitutes him in such a way that he can live in harmony with his environment. It arranges the environment in such a way that it raises him like a loving nurse. The sun, the moon, the stars, water and earth, the night and the day, the seasons of the year, the clouds, wind and rain, the treasures beneath the earth and on its surface, in other words all the forces of nature, use their energy and resources in providing well-being and peace of mind for him. Such a relation and harmony can be discovered among all phenomena and also between man and his neighbors near and far, as well as within man’s own habitat.
