Medicines are accompanied by leaflets explaining what illnesses they are designed to cure, how they should be used and what their basic formulae are. But man is born into the world in such a condition that he knows neither what he is nor why he has been put here. No convenient handbook accompanies him, neither are there any signboards fixed to the summits of the mountains to give him directions or to provide him with answers to his questions. Man has, in consequence, formed strange opinions about himself, the earth and the sky, being ignorant of the essential reality of life. When he examines his own being, it appears to him as an amazing accumulation of intellectual and physical powers. Yet, he did not will himself into being, nor did he play any part in the making of himself. Then he looks at the world outside himself and a universe of such extreme vastness, that he can neither encompass nor traverse it, nor can he count the innumerable treasures it contains. What is all this, and why is it there? Where did this world start from and where will it all end? What is the purpose of all this existence? He finds himself completely in the dark on these subjects. Man has, of course, been given eyes, but all his eyes can do is see the outside of things. He has intelligence, but the trouble with human intelligence is that it does not even know about itself. Up till now, man has been unable to find out how thoughts enter the human mind or how the mind functions. With such inadequate faculties, he is neither able to arrive at any sound conclusion concerning himself, nor he is able to understand the Universe.
This riddle is solved by the Book of God. Today, the Qur'an is the only scripture beneath the heavens about which we can say with complete conviction that it gives us definite knowledge concerning all the realities of life.
Those who have tried to understand the Universe without recourse to the Book of God are just like those blind people who try to find out what an elephant is by touching different parts of its body. One will touch its leg, and think he has found a pillar. Another will feel its ear, and think it is a winnowing basket. Its back will be proclaimed a platform, its tail a snake and its trunk a hosepipe. But where in all this is the elephant? No matter how these blind people put together their findings, they cannot arrive at the correct answer. This is the eternal predicament of all atheist philosophers and thinkers. In their attempt to fathom the nature of reality in the universe, they have failed to be guided by true knowledge. As a result, their conclusions have been like those of a man, fumbling in the dark, and just hazarding wild guesses as to the nature of his surroundings, without ever truly understanding it.
There have been people in this world who have devoted their entire lives to the quest for Truth, but who, in their desperation at being unable to find it, have even taken the extreme step of putting an end to their lives. And then there have been others who sought the Truth but who, having failed to find it, settled for a concocted philosophy based on pure conjecture. While the latter, mistaking conjecture for reason, compiled their conclusions and presented them to the world as Truth, the former saw speculation for what it was, rejected it, then – anguished at their own ultimate helplessness – opted out of this mysterious world.
Both groups were denied True Knowledge, for, in reality, no one can understand the secret of life without the help of the original Keeper of the Secret. True, man has been given the capacity to think and understand. But this capacity is little better than an eye which can see only so long as there is some external source of light. In pitch darkness, this self-same eye cannot see anything whatsoever. Only when a light is switched on, does everything become clearly visible. The human intellect, like the eye, needs the light – the light of God's revelation – if it is not forever to grope in the dark. Without God's revelation, we can never arrive at the truth of things.
Therefore, the Quran is essential in man’s search for truth.
