Anatomy has discovered that small intestines are the longest part in the digestive system, of about 5 meters long. The walls of intestines consist of 3 layers:
1- The external stratum (serum stratum): its membrane is soft and wet due to the secretion of a serum liquid.
2- The medium stratum (muscular stratum).
3- The internal stratum (mucosa stratum): it consists of a mucosa plate and circular or ring folds full of villi, and contains intestinal glands and lymphatic vesicular.
It has been found out that the abdominal cavity is lined with the peritoneum which is fed through the wall nerves feeding the skin, and the muscles of chest and abdomen. These nerves are affected by touch and heat. The viscera have no nerves for pain or sensation. Therefore, when the abdominal wall is anaesthetized locally, and the abdomen is open, no sensation of pain or disturbance is felt in the intestines if held, cut or even burned. But when the intestines are cut or perforated for any reason, its contents come out into the cavity surrounding the viscera, and which is rich in sensitive nerves, the pain is then very severe and the abdomen of the patient is in a state called Board Like Rigidity. It is an emergency surgical state that requires an immediate operation.
Perforated intestine causes severe abdominal pain
In Quran, Allah the Almighty says about the torment of hell fire;
“Such are given to drink boiling water, that tears their bowels asunder.”
The Holy Quran threatens the unbelievers of hot water that tears their bowels. The reasoning underlying this threat has recently become evident. It has been discovered that intestines are not affected with heat. But if they are cut, hot water therein comes out into the peritoneum which is fed through the wall nerves feeding the skin, and the muscles of chest and abdomen. These nerves are affected with touch or heat, so the hot water, after intestines are cut, causes the highest degrees of pain.
So the outer torment felt in the skin, is different from that felt in the inner intestines, due to the difference in the nature of skin structure. The feeling of former torment cannot be maintained unless the roasted skin is exchanged with a new layer, while in the case of intestines, torment is felt only by cutting the intestines with hot water. Torment is yet continuous:
“As for the unbelievers, theirs shall be the fire of Gehannam (hellfire); they shall neither be done with and die, nor shall its chastisement be lightened for them, even so We recompense every ungrateful one.”
Thus the Quranic scientific miracles are crystallized. Feeling of pain as perceived in medical facts are very much compatible with the statements of the Holy Quran.
