It is quite hard to upset the equilibrium between the elements that are essential to life on Earth. You do not suddenly start breathing carbon monoxide or floating away from your chair into space due to a decrease in the force of gravity. Sunlight does not suddenly damage your eyes and skin, and oxygen levels do not rise so high that your lungs begin to burn. There are many reasons for this. However, the interesting thing is that all balances assumed their present forms due to the Big Bang, defined as the explosion of a single point of zero volume that contained all matter in the universe.


  Countless conditions combined in order to maintain this equilibrium. For example, if the rate of the universe's post-Big Bang expansion had been just 1 in 1 billion billion (1/1018) different, the universe would not have emerged. If the universe had expanded just slightly more slowly, it would have imploded due to the gravitational force; if it had expanded a little more quickly, all cosmic matter would have dispersed and vanished. If a 1/1018 difference in the explosion's speed had arisen just when that speed had reached a particular level, the equilibrium in question would have been destroyed. If just one of these minute variations had arisen, the universe would have disappeared.

  Let's take a look around us. Everything is in an extraordinary state of stasis, calm, and perfection, because nothing in the universe is coincidental. In fact, everything depends on a flawless and perfect level and the extraordinarily delicate balances created and set into motion by Almighty Allah, Who rules everything, created a flawless artistry and miracle via a single explosion, and is all-giving:

"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)
