Human beings cannot control the beating of their hearts, manage their salivary glands while eating, or remember to breathe every few seconds. Countless such vital functions take place without any human intervention at all. Yet despite this lack of personal supervision, all bodily systems function flawlessly.
An individual’s chromosomes contain information regarding that person. Each of the forty-six chromosomes in the nucleus possesses genes that, utilizing the framework of the blueprint contained therein, construct each bodily organ according to His will. For example, a person’s skin is controlled by 2.559 genes, the brain by 29.930, the eye by 1.794, the salivary glands by 186, the heart by 6.216, the breast by 4.001, the lung by 11.581, the liver by 2.309, the intestines by 3.838, the skeletal muscles by 1.911, and the blood cells by 22.092 genes.
The way that countless tiny components hidden inside a cell that is invisible to the naked eye supervises a person’s bodily systems is a great miracle. It is extraordinary that this system is never interrupted and that the same genes control the same systems and organs in every new-born human being.
Despite the vital functions for which they are responsible, genes consist of nothing but blind and unconscious atoms. Therefore, how can the superior consciousness and flawless regulation visible here belong to them? Each gene, which is an amazing marvel of Creation, acts according to His will instead of some posited model. Proof for this statement is all around us, for how could an unconscious gene accomplish such miraculous deeds if Allah did not will it to be so? This state of affairs makes itself crystal clear in every detail in the universe. Everything is a manifestation of Allah’s sublime Creation. Genes are able to control everything related to the body’s systems at every moment.
This sublime control belongs to Allah, the Elevated One, the true Lord of this entire system:
Allah, there is no deity but Him, the Living, the Self-Sustaining. He is not subject to drowsiness or sleep. Everything in the heavens and Earth belongs to Him. Who can intercede with Him except by His permission? He knows what is before them and what is behind them, but they cannot grasp any of His knowledge, except for what He wills. His Footstool encompasses the heavens and Earth, and their preservation does not tire Him. He is the Most High, the Magnificent. (Surat al-Baqarah, 255)
