PAIN RECEPTORS IN THE SKIN 

It was thought that the sense of feeling and pain was dependent only on the brain. 
Recent discoveries however prove that there are pain receptors present in the skin, without which a person would not be able to feel pain. 

When a doctor examines a patient suffering from burn injuries, he verifies the degree of burns by a pinprick.
 If the patient feels pain, the doctor is happy, because it indicates that the burns are superficial and the pain receptors are intact. 

On the other hand, if the patient does not feel any pain, it indicates that it is a deep burn and the pain receptors have been destroyed.

The Qur’an gives a clear indication of the existence of pain receptors in the following verse: 
“Those who reject our signs, We shall soon cast into the Fire; 
as often as their skins  are roasted through, 
We shall change them for fresh skins, that they may taste 
the Penalty:for Allah is Exalted 
in Power, Wise.” 
[Al-Qur’an 4:56]

Prof. Tagatat Tejasen, Chairman of the Department of Anatomy at Chiang Mai University in Thailand, 
has spent a great amount of time on research of pain receptors.

 Initially he could not believe that 
the Qur’an mentioned this scientific fact 1,400 years ago. 
He later verified the translation of this particular Qur’anic verse. Prof. 
Tejasen was so impressed by the scientific accuracy of the Qur’anic 
verse, that at the 8th Saudi Medical Conference held in Riyadh on the Scientific Signs of Qur’an and Sunnah, he proudly proclaimed in public: 
“There is no God but Allah and 
Muhammad (pbuh) is His Messenger.”
