All the time you have been reading this book, as well as at the present moment, the molecules in your body have been going about their activities constantly. Some have measured your calcium levels and in various ways, have made good any calcium deficiency. Others have begun collecting amino acids necessary for protein production. Some have divided your DNA’s double helix in two in order to copy it, while others have waged war on bacteria and viruses entering your body and thus protected you against disease.
Others have worked to maintain your body temperature within normal range, and still others have expelled waste products from your body. Countless other processes as well have been taking place, all at the same time.
You have done nothing to regulate all this, to initiate it, nor to put an end to it. You have just sat in your chair, reading.
This book, besides introducing you to the infinite might, knowledge and intelligence of God, has described just a few of the proofs that He is the Compassionate and Merciful. God has created human beings and all other living things with flawlessly functioning systems. As is revealed in the Qur’an, God:
... created everything and determined it most exactly. (Surat al-Furqan, 2)
As can be seen from every example cited in this book, molecules too small to be seen with the naked eye have great abilities and responsibilities. These molecules must have been created with all the characteristics necessary for them to fulfill all these attributes. The examples we have provided are no doubt manifestations of the existence, omniscience and creative artistry of God.
Almighty God, Lord of the finest titles, says in the Qur’an:
... God has power over all things and that God encompasses all things in His knowledge.’ (Surat at-Talaq, 12)
They said "Glory be to You!
