Have you ever thought about your own body to see the gifts and intelligence in? Indeed Allah is of boundless mercy, with all those blessings which are manifest and all that of those that can not be undrestood by human little knowldge. To name a few of those manifiest mercies to people from the part of Allah , Professor Hossein Ansaryan glanced casually at these issues in a apart of his book under the name of “Commentary on Kumayl Suplication”.
Scientifically, the system of human brain is the most awesome machine and performs duties that the most developed human-made machines are unable to complete. One of the duties of the brain is to record various events in the memory. Human memory is related only to a small part of the brain. For showing the memory capacity, an example has been repeatedly given:
Suppose a fifty-year old man wants to write all his memories collectively. For this he will need 160 million large size newspapers that are printed with small in twenty pages each. In many respects, the mechanism of remembering the memories resembles that of the tapes of voice recorders. The difference is that the power of brain tapes is provided by body nerves and they need not to rotate.
If we want to build a machine that performs the work of human brain more or less, we should make an apparatus two times the largest buildings in the world, allotting all the electricity made by the water of world largest fall for its power. Because the electric lamps and wires make the machine hot, all the water of the supposed fall should turn around the machine. The invented machine will not after all perform all the thinking duties of an ordinary human brain.
The command of sucking milk from the mother breast is issued from the child’s brain to its lips, and the child feeds from its mother’s breast calmly and with no mistake. In the mother body, there is an automatic chemical factory that turns her blood into a useful and delicious food, suitable for the infant’s digestive system. When the fetus is created in the mother womb, the suckling factory revives in the mother body and begins work. As the fetus grows, this factory gets more active until it produces suitable milk for the baby at the birth. After the birth, as the child grows up, and its digestive system becomes stronger, the produced milk changes accordingly.
The precious product of this factory is assembled in two sources on the mother breast and leaks out of their nipples by the baby’s sucking and becomes part of its body. The size of the nipples is appropriate for the baby’s mouth, including tiny openings that open by the baby’s sucking and are automatically closed afterwards, not to waste the milk.
All these interesting events and alterations for the sake of humans are nothing but Allah’s infinite Mercy and unlimited blessing. Human being should ponder in these phenomena, praise the Almighty, and beg Him for spiritual blessings.
The Respiratory System
Human lungs inhale and exhale the air for approximately 500 million times, during a typical lifetime. In the respiratory system, there are hundreds of thousands of glands that leak out a sticky liquid to absorb the harmful dust particles entering the lungs when breathing. If this liquid did not exist, the particles obstructed the respiratory pipes in a few seconds, causing death.
Also there are tiny hairs in these pipes that constantly clean them. These hairs clean all the pipes twelve times per second, and send the harmful particles into the digestive system in which they become ineffectual.
The respiratory pipes transfer the air to 750 million bags inside the lungs in which the carbon dioxide is taken from the blood and oxygen is replaced instead. The respiratory system, with such a small size, important duty, and amazing process is but one part of “كل شيء” (everything) that are embraced by Allah’s Mercy.
