If we look at the order of creation we can see that a vast and comprehensive equilibrium prevails among all physical phenomena. This is evident in the regularity of the atoms the haste of the electrons the rotation of the planets and the movements of all bodies. It is visible in the mineral and vegetable realms in the precise relations that exist among the organs of a living being in the balance among the inner components of the atom in the equilibrium among the vast heavenly bodies and their finely calculated forces of attraction. All these forms of balance and equilibrium together with the other precise laws that science is still seeking to explore bear witness to the existence of an undeniable order in the universe one which is confirmed by mathematical equations.
Our veracious Prophet has expressed this universal justice and comprehensive equilibrium the fact that nothing g is irregular or out of place in this concise and eloquent statement: It is true equilibrium and symmetry that maintain the earth and the heavens.
The Quran attributes the following words to Moses peace be upon him and our Prophet: Our God is the one who endowed all things with the needful and then guided them for the continuation of their existence. (20:50)
In this short sentence Moses expounds to the Pharaoh the manner in which the world was created together with its orderliness and beauty which are among God's signs. His aim was to save him from his erroneous thoughts and help him perceive the existence of a just and divinely instituted order in the universe.
One of the norms ruling ineluctably over nature is therefore order and justice and all things by virtue of their subordination to the norms and laws of nature are engaged in the process of evolution toward perfection that is specific to each of them. Any deviation from this universal pattern of order and the relations founded upon it would result in confusion and chaos.
Whenever some irregularity occurs in nature phenomena themselves evince a reaction and inward or outward factors emerge to remove the barriers to development and reestablish the order needed to continue on the path to perfection.
When the body is attacked by microbes and other factors of illness white globules begin to neutralize them in accordance with ineluctable norm. Whatever medicine may be prescribed is an external factor aiding the white globules in their task of neutralization and re-establishing equilibrium in the body.
Finally it is impossible that God Whose love is infinite and Who unstintingly grants His favors to His servants should perform the slightest unjust or inappropriate act. This is indeed what the Quran proclaims: It is God Who has made the earth a place of abode for you Who has raised the heavens created you in the best of forms and given you delicious and pleasing foods as sustenance. This is God your Lord. (40:64)
