He Who created the seven heavens in layers.You will not find any flaw in the creation of the All-Merciful. Look again – do you see any gaps? Then look again and again. Your sight will return to you dazzled and exhausted! (Surat al-Mulk, 3-4)
There are innumerable factors which are required for the continuation of life on Earth, and it is very difficult for these factors to be destroyed. You do not begin to breathe carbon monoxide all of a sudden, nor are you lifted off the chair you sit on and begin floating away towards outer space. The light coming from the Sun does not damage your eyes or skin in a sudden manner, nor is the oxygen present in the atmosphere so excessive that it would burn your lungs.
The causes that ensure this are great in number; what is noteworthy to consider is that all of these causes came into existence with the explosion of a single point with zero volume that contained all the matter of the universe inside it. This explosion was the Big Bang, and all of the balances which now exist were created with this explosion.
There are many factors that have come together in order for the delicate ratio that ensures stability in the universe to come into existence. For example, if the speed of expansion right after the Big Bang had been one in one billion times a billion (1/1018) different, the universe would not have come into existence. Had the expansion been a little slower, the universe would have collapsed due to the intense gravitational forces; conversely, had it expanded a little faster, then the early cosmic material would have been scattered and dispersed. If there had been as little a difference as 1/1018 in the speed of the explosion at a certain point, this would have been sufficient to utterly destroy the balance in question.
If only one of these almost insignificant changes had occured, the universe as we know would have been destroyed at the very moment of its birth.
Take a good look around you; the house you live in, the street you live on, the very planet you call home, and the heavens above; everything demonstrates the most extraordinary stability, calmness, and perfection.
Nothing in this world is coincidental. Nothing develops at random, or in an out-of-control fashion, nor without consciousness. Everything is wholly dependent on a flawless and perfect ratio, and balances of the most extraordinary sensitivity and sophistication.
The Owner of all these is Almighty Allah, the Owner of Might and Grace, He Who created a flawless work of miraculous art by making the cause of all things a single explosion in the vastness of space.
