Dear Br. Jawaid,
All laws are not known, and will not be known.
The known laws are not always correct. ( Human wisdom limits).
The one's not known today could be taken as miracles. Ex: The colored light beams on the north pole horizon were taken as mysterious as few years back, but now the reasons are known. So its not a mysterious.
If you believe and accept that a prophet received or perceived divine message called Wahee directly from Allah, the its against known physical laws on this earth. Can you explain that.
If you believe in direct wahee or message , then you will negate your own post. If you don't, then was there no messenger from your point of view.
My answer to above mystery will be a guess of today, that is, Its the Neurons, which may receive or decode out side energy, sub-carrying a message. To do that, one have to be a chosen one ( The Prophet) from Allah, subhana wa Taala.
One day it will be discovered, and its going to be hidden in energy field.
