For a long time we have been thinking that the only function of the human heart is to beat and pump blood, but no, the human heart is an independent and complete organ as we call it independent and complete. Modern science has confirmed in the light of research that the heart has its own brain, the amount of which is small but the presence is clear.

And this has already been told to us by the great scientist and teacher, Hazrat Muhammad (SAW) in this way. "Indeed, there is a lump of flesh in the human body, so that if it is right, then the whole body is right, and if it is bad, then the body is bad. Some say that the heart is an autonomous organ. The heart is likened to a commander while the rest of the limbs are considered to be its obedient soldiers.

“The human heart” and “modern science” from the verses of Tafsir al-Bamrur Zamana (Hadith) and also the verses in this (Qur'an) which will be understood with the passage of time (ie with the advancement of scientific knowledge). Modern science and research, in the light of observations and experiments, have recognized that inside the human heart there is a "small brain" which consists of about forty thousand (4) nerve cells, nerve cells are those cells. Which make up the brain.

This has been confirmed by a Canadian medical doctor (Dr. J Andrew Armour). According to Dr. Armor, the 40,000 cells in the heart are enough to make the heart the king and sovereign of the human body. Based on research, observations and evidence, he successfully founded a new medical field called Nervous Neuro-cardiology. Dr. Armer named the nervous system of the heart (A Little Brain in the heart).

In a statement, Dr. Armor also stated that the human heart is an independent organ. Interestingly, when the human brain sends signals to the heart to make the heart beat faster or slower, the heart reacts at will. Sometimes the heart's reaction is just the opposite. The small heartbeat of the heart is a bit more because it can think in a certain way which gives the heart the strength to make decisions before the brain in emergency situations.

The tiny brain of the heart is self-supporting and can survive for a specific period of time even without signals or help from the brain. Which is a great proof of sovereignty. The small brain of the heart also has the ability of short term memory. It not only stores information for a fixed period of time, but also makes it visible. However, the interconnectedness of the heart and the brain cannot be considered essential or unnecessary because the human body functions according to the principles of a specific set of systems called coordination and control.

In short, man is one of nature's greatest masterpieces. Because, looking at the little saddle, its twenty-four hour uninterrupted throbbing and blood transfusion, again the brain in it, and the ability to think!
