Take a look around you from where you sit. You will notice that everything in the room is made: the walls, the upholstery, the ceiling, the chair where you sit, the book you hold in your hand, the glass on the table and countless other details. None of them happen to exist in your room of their own accord.
Even the simple loops of the carpet were made by someone: they did not appear spontaneously or by chance.
A person who is about to read a book knows that it has been written by an author for a specific reason. It would not even occur to him that this book might have come into being by chance. In the same manner, a person who sees a sculpture has no doubt whatsoever that it was made by a sculptor.
And not just works of art: even a few bricks resting on top of one another make one think that they must have been brought to rest just so by someone within a certain plan. Therefore, everywhere where there is an order either small or big a founder and protector of this order must also exist. If, one day, somebody came forward and said that raw iron and coal came together to form steel by chance, which in turn constructed the Eiffel Tower again by chance, would not he and those who believed him be regarded as insane?
The claim of the theory of evolution, the unique method of denying the existence of Allah, is no different than this. According to the theory, inorganic molecules formed amino acids by chance, amino acids formed proteins by chance, and finally proteins formed living creatures again by chance. However, the probability of a living creature being formed by coincidence is less than the probability of the Eiffel Tower being formed in the same manner, because even the simplest human cell is more sophisticated than any man-made structure in the world.
How is it possible to think that the balance in the world came about by coincidence when the extraordinary harmony of nature is observable even with the naked eye? It is the most unreasonable claim to say that the universe, each point of which suggests the existence of its Creator, has come into being on its own.
Therefore, there should be an owner of the balance visible everywhere from our body to the farthest corners of the inconceivably vast universe. So, who is this Creator that ordained everything so subtly and created all?
He cannot be any material being present within the universe, because His must be a will that existed before the universe and created the universe thereupon. The Almighty Creator is One Whom everything finds existence, yet Whose existence is without any beginning or end.
Religion teaches us the identity of our Creator Whose existence we discover with our reason. Through what He has revealed to us as religion, we know that He is Allah, the Compassionate and the Merciful, Who created the heavens and the earth from nothing.
Although most people have the capability to grasp this fact, they spend their lives unaware of it. When they look at a landscape painting, they wonder who its painter is. Later, they praise the artist at length for his beautiful work of art. Despite the fact that they face numerous originals of that painting the moment they turn around, they still disregard the existence of Allah, Who is the only owner of all these beauties. In truth, not even a lengthy research is needed to understand the existence of Allah. Even if one had to live in a room from the time he was born, countless pieces of evidence in this room alone would be enough for him to grasp the existence of Allah.
The human body so overflows with evidence that it could not be contained in many multi-volumed encyclopedias. Even giving a few minutes of conscientious thought to it all is enough to understand the existence of Allah. The present order is protected by Allah and maintained by Him.
The human body is not the only food for thought. Life abides in every square millimetre of the earth, be it observable by men or not. The world overflows with many living beings, from unicellular organisms to plants, from insects to sea animals, and from birds to human beings. If you take a handful of soil and look at it, even therein you can discover manifold living creatures with diverse characteristics. The same is true also for the air you breathe. Even on your skin, there are many living creatures whose names are unknown to you. In the intestines of all living beings are millions of bacteria or unicellular organisms that help digestion.
The animal population in the world is many times greater than the human population. When we also consider the plant world, we see that there is not a single spot on the earth where there is no life. All of these creatures that are spread over an area of millions of square kilometres have different body systems, different lives and different contributions to the ecological balance. It is preposterous to claim that all these have come into existence by chance with no aim or purpose. No living being has come to exist through its own accord or effort. No coincidental happening can ever result in such complicated systems.
All of this evidence leads us to the conclusion that the universe works with a certain consciousness. What, then, is the source of this consciousness? Surely it is neither the living nor the non-living beings in it. Nor can they be the ones that maintain the harmony and preserve the order. The existence and glory of Allah reveals itself in countless proofs in the universe. In fact, there is not even a single man on the earth who will not accept this evident reality from the heart. Yet they still deny it in iniquity and arrogance though their souls are convinced thereof as stated in the Qur'an.
(And they denied them, though their souls acknowledged them, for spite and arrogance. Then see the nature of the consequence for the wrong-doers!). (Surat an-Naml, 14)
This book is written to point out this reality from which some people turn away because of its being at odds with their interests, and also to disclose the frauds and senseless deductions on which some untrue allegations stand. This is why many diverse subjects are tackled in the book.
Those who read this book will once more see the indisputable evidence of Allah's existence and witness that Allah's existence encompasses all things: the reason knows this. Just as He has created this all-pervading order, He is the One Who also maintains it incessantly.
