If a Limb Aches, the Whole Body Suffers

An-Nu mân ibn Bashỉr &, narrated that Allah's Messenger said, "You see the believers as regards their being merciful among themselves and showing love among themselves and being kind to each other, resembling one body, so that, if any part of the body is not well then the whole' shares the sleeplessness (insomnia) and fever with it.'
Explanation of the Hadith
In a critical scientific research, Dr. Maher Muhammad Salim (A Muslim doctor) highlights some scientific signs mentioned in this hadith that have only been discovered by modern science in the past few years. One of these signs is that the ailment of the sick organ is a true complaint and not mentioned by way of metaphoric implication. As soon as an organ is affected, nerve sensory pulses are sent from the sick or injured rea, calling out for help from the sensory centers and the inviri: intary control centers in the brain. Moreover, a large ame it of hormones and other chemical materials are
(Reported by iii.; al-Bukhari, “Book of al-Adib (good manners).”)
released from the sick organ with the first blood drop coming out of it, the damage of a tissue cell or with the invasion of a microbe releasing its poisons into its tissues and cells. As soon as those chemicals and hormones are sent to central areas in the brain, the latter sends its order to the body organs that control the biological functions of the body, in order to provide aid to the affected organ according to the nature of its injury or disease.
Soon after the infection or injury takes place, the organs in control of the biological process start to call on each other for help. Sensory centers call the control and alert centers in the hypothalamus. This in turn calls upon the pituitary gland to secrete hormones that call on the rest of the endocrine glands to secrete their hormones, which urge all the body organs to save the complaining organ. Therefore, it is a real complaint, and a true call rather than a metaphorical one. The call in this case means that every part of the body utilizes its utmost energy to save that complaining part. The heart, for example, starts beating faster, to help the blood circulate and reach the injured organ. At the same time, the blood vessels in that injured organ expand, while other vessels in the rest of the body contract in order to send this affected area, the energy, oxygen, antibodies, hormones and amino acids that help it resist the infection or injury and heal quickly. This is a summary of what the various body organs do, namely the heart, the liver, the endocrine glands, the muscles and others, constituting a kind of teamwork which could not be described in a word more eloquent, accurate or comprehensive than “Tadâ âl!”" (share jointly). l Literally means a mutual call or summoning (between the organs), This sharing demands a high degree of sacrifice and exertion of great efforts from all body limbs, as all organs, systems, tissues and glands are required to break up part of the stored fats and proteins, in order to provide aid to the injured organ. This constant flow of sacrifice continues until the rescue process is over; when the injury or disease is under control, and the infected tissues and cells are cured. It continues until the whole body is either totally cured or totally damaged resulting in death. These facts were only discovered by science a few years ago. Taking into consideration that this hadith refers to these facts in such a comprehensive way, is a clear testimony that the Prophet 3 was given the keys of eloquent speech and that he was directly connected to the Divine Revelation and taught by the Creator of the heavens and earth. No wise man would ever believe that the source of this Prophetic knowledge could be anything but Divine Revelation. This knowledge was announced by the Prophet 3, more than 1400 years ago, in a nation most of whom were illiterate, and at a time when all people throughout the world were oblivious of such scientific facts. The best means to preach Allah's true religion is by using these scientific aspects from the Glorious Qur'an and from the Prophet's Ahadith; because we are living in the age of scientific technology where we are witnessing a clash of civilizations as well as political, racial, religious conflict and bigotry.
