The liver is the only human internal organ capable of the natural regeneration of lost tissue. As little as twenty five percent (25%) of a liver can regenerate into a whole liver. The mechanisms by which the liver regenerates itself is still a matter of serious research. This feature of the liver was first discovered by two surgeons at The Mayo Clinic in 1931. One astonishing feature of the liver is the very rapid division of its cells while still carrying out its functions flawlessly. It is more amazing how, once the regeneration function is performed, the cell division ceases suddenly, as though through a consensus of the cells. At this point the following questions come to mind:
- During the multiplication process, how do the cells know when to proceed and when to stop?
- Who orders them to stop or proceed?
- If they do not take the order “stop” from somewhere, how do the liver cells themselves, determine when to stop growing, so as to not grow so large as to damage other internal organs?
There can be no doubt that it is impossible for cells, which do not have an independent consciousness, to perform even one of these functions. It is Allah Who creates these miraculous functions, regulates them and gives the due orders. In the Qur’an Allah relates that it is Allah Who regulates every system in this world and that people need to ponder over these systems:
It is Allah Who created the seven heavens and of the earth the same number, the Command descending down through all of them, so that you might know that Allah has power over all things and that Allah encompasses all things in His knowledge. (Surat at-Talaq, 12)
