Miracle

[paulpablo]

If you think that people knew that pain resides in Skin not in heart or in brain then why do not you Quote a reference from 6th or 7th century which clearly proves that people were aware of the fact that burning a skin to a particular extent can take away its ability to feel the pain?

I'm not making any positive claims regarding miracles.  I'm saying I doubt any supernatural miraculous things exist.  You say they do exist and that the verse you showed me is a miracle.  You can't just say something is a miracle then ask me to find 6th or 7th century sources to prove you wrong.
It's up to you to prove to me that people in the 6th or 7th century had no knowledge of the symptoms of 3rd or 4th degree burns.
They wouldn't have to know where pain resides, where it is created, the verse doesn't mention where pain resides or anything like that in the verse you have shown me.
 You prove to me simply that people in the 6th and 7th century didn't know that skin goes numb when it is severely burned.  The only knowledge that you would need to be able to write that verse is that skin which is destroyed by fire feels no pain.
So just to clarify don't show me links that say they believe pain originated in the brain or in the heart, even if pain originated from the brain they could still know that burning skin hurts, and if they knew about 3rd or 4th degree burns they would also know that the skin ceases to feel pain at a certain point after being burned badly enough.

To put it even more simply, nothing you have posted proves that people during the time of Muhammad didn't know being burned badly causes numbness.
