Another miracle mentioned within the Qur’an is the barrier between the two seas. Yes, both sea’s have their own temperature, salinity and density. No matter how much they clash, the large waves and tides, you will discover the sea’s as two, as if there is an invisible barrier between them.

The Qur’an mentions:
“It is He Who has Let free the two bodies Of flowing water: One palatable and sweet, And the other salty and bitter; Yet has He Made a barrier between them, And a partition that is forbidden To be passed.” (Qur’an 25:53)

I was amazed when I got to know about the two sea’s which do not mix. During a period when there was little knowledge of physics, and of surface tension, or Oceanography, this truth was revealed in the Qur’an
We ask for miracles, their mentioned within the Qur’an, the parting of the two sea’s being one of them, but we still deny or look for information to prove the verses incorrect. If this is not enough, the magic continues, the Qur’an reveals many more signs to us which will amaze you.
