Would you believe a man if he tells you that there is a store which is running smoothly but has no salesman, storekeeper or someone to look after it? Or would you believe him if he told you that the chair in front of you assumed its present form all by itself?

Now, if there is no way to persuade you that an ordinary store could run without a storekeeper or a salesman, or that a chair could assume its form without a carpenter's skill, could you possibly accept the thesis that the universe is without a creator or master? In the wonderful scheme of the universe, with countless living creatures, the sun, moon, stars and planets function with the utmost precision. Vapor rises from the oceans and turns into clouds; the winds blow these clouds to the distant comers of the earth, then the vapor condenses into water and falls on the earth as rain which brings dead soil to life and helps the growth of various kinds of grains and other crops, and different varieties of fruits and flowers. The fruits have different flavors, though they grow in the same place, using the same water. 

Now, could any sensible person believe that this vast and integrated system sprang into existence and runs without a master or governor? 

We do not hesitate to dismiss a person as lunatic who considers that a thing as insignificant and small as a chair or a piece of cloth came into existence by itself-, should we then agree with someone who states that the earth sprang into existence automatically, the animals came to life by themselves and even the most wonderful and complicated of the living beings - the human being - came into existence without a creator? 

Look at the human body and the millions of systems and sub-systems working with the most wonderful cooperation and packed most efficiently in that small body.

Have you even pondered how the human fetus forms and develops in the tiny workshop of its mother's womb? At a moment of which neither the father nor the mother is aware, two small life germs unite, then in nine months, they develop into several organs and parts of the human body in the appropriate places. Every part, large or small is precisely where it should be. Only a person out of his wits could say that this wonderful system of life came into being, and has continued for countless generations without a Wise, Powerful Being possessing vast knowledge and unrivalled powers of creation.

Suppose an earthquake occurs and all the different solutions in a lab fall and mix together. It would be a very strange coincidence if such a mixture produces a new medicine that cures a certain disease. 

Now let us look at the probability of forming a protein molecule assuming that all the elements are already in existence. The Swiss mathematician Charles Eugene Jai calculated this probability. He took the protein molecule as his sample, but he simplified the case by considering his molecule to contain 2,000 atoms instead of 34,500 and to consist of two types of atoms instead of four major ones. The value of probability is determined by the size of the material necessary for such a reaction to take place and he found that the probability of forming that simplified protein molecule was approximately 1/2 x 10³²¹ .The size of the material necessary for that almost zero probability was a sphere whose diameter was approximately 6 x 10¹⁷⁶ miles and this sphere is approximately 10⁶³ times the imagined size of the universe. He found also that the time necessary for such a molecule to form was 10²¹³ billion years which is by far greater than the hypothesized age of the earth which is only two billions years. So the size and time factor would make it impossible even to form one protein molecule.

Have you ever heard of a school with two principals, or a department with to chairpersons, or an army with two commanders-in-chief or a country with two presidents? In any event could any institution under a dual control be run effectively? Look at the millions of planets and stars: their conduct and movement show an extremely strict adherence to a certain uniform set of rules and regulations. Their distances and directions in relation to one another are set and even the slightest alteration of this scheme will upset the whole system and cause chaos. 

The rules they are abiding by are so uniform that we research to find mathematical formulas describing them. If the universe had been governed by several or even two gods, its affairs could not possibly have been run so regularly and efficiently and we would have seen the chaos stemming from contradicting orders and rules. If even a small school cannot accept two principals at one time, how could the vast realms of the heaven be run by more than one Sovereign? 

Now when God is the sovereign of the universe, is it not logical that you submit willingly to His commands and model your life according to the way of life He set for mankind? You can find that way of life explained fully in Islam.
