Prophet's Guidance on treating narcolepsy (STUPOR)
Abu Ubaid said in his book "Gharib ul Hadith" that some people passed by a tree that they ate from and they were soon immobilized, just as if a wind had swept through by them and froze them. Prophet Muhammad Sallallaho Alaihe Wasallam said: "Cool some water in water skins and then pour the water on them between the two Azaanain (the Fajar call to the prayer and the Iqamah)".
Prophet Muhammad Sallallaho Alaihe Wasallam mentioned water skins because they cool the water more than clay containers. Furthermore, he called the Iqamah and Azan in this Hadith.
Some doctors stated that the remedy that our beloved Prophet prescribed in Hadith is one of the most effective against narcolepsy if it occurs in the area of Hijaz, which is a hot dry land. The inhabitants of that area have a weak instinctive heat. Pouring cold water on the people afflicted by narcolepsy during the above mentioned time, which is the coolest time of the night, will cause the instinctive heat that is scattered throughout the body to be energized and accumulate in the inner parts of the body where the ailment resides. The powers of the body will then concentrate on expelling and resisting the ailment by AIIah's Will.
If it were Galinus or Hippocrates who had prescribed this remedy the doctors would have been amazed by its perfect effectiveness.
The term KHADRAN الخدران is translated as Narcolepsy which is a sleep disorder, but a better translation for KHADR is Narcosis or STUPOR.
Stupor is the lack of critical cognitive function and level of consciousness wherein a sufferer is almost entirely unresponsive and only responds to base stimuli such as pain. Being characterized by impairments of reactions to external stimuli, it usually appears in infectious diseases, complicated toxic states, severe hypothermia, mental illnesses (e.g. schizophrenia, severe clinical depression), vascular illnesses (e.g. hypertensive encephalopathy), neoplasms (e.g. brain tumors), and vitamin D deficiency and so on.
