Each liver cell carries out some 500 different chemical processes. Somehow, they are aware of each activity taking place in the body’s circulatory, digestive, excretory, and other systems. Due to these tasks that they perform, each cell is the site of intense and continuous activity.
If any part of the liver is damaged or extracted, its cells immediately switch to a new function—high-speed multiplication—to repair the affected part. As a result of the cells’ extraordinary abilities, the liver is the only bodily organ that can reconstitute itself. When the liver regains its normal size and is fixed, the cells suddenly cease this activity.
There is no difference between liver cells and those in your finger tips, for both sets carry exactly the same information. What makes them different is what part of that information they use. A single cell, invisible to the naked eye, knows that the reproduction process has to begin and so begins copying itself. When it learns that the regeneration process has been completed, it and all other cells stop this activity in a perfectly orderly manner that betrays no haphazardness. During reproduction, no cell decides to postpone the other functions and thereby cause interruptions in the system. No new copied cell is told what to do. Nonetheless, every new cell unhesitatingly begins its work inside the liver.
This wide-ranging system does not belong to human beings. For only the Omniscient Allah Who creates all living things and their cells, and Who controls and supervises them at every moment, can perform such a miracle. This miraculous system is the work of Almighty Allah, Who remains unchanging, Omniscient, and All-powerful:
O humanity, if you are in any doubt about the Rising, know that We created you from dust then from a drop of sperm, then from a clot of blood, then from a lump of flesh, formed yet unformed, so that We may make things clear to you. (Surat al-Hajj, 5)
