The Merging of Seasand Their Distinction

​

Allaah The Almighty Says (what means):

{He merged the two seas. They meet. Between them is a barrier. They do not transgress.}

(Quran, 55:19-20)

Scientific Analysis

Seas were not known to comprise of various kinds of water. Instead, the prevalent belief was that each sea had a single nature. This was proven untrue in 1873 by the Challenger expedition (1872-1876).

It was only in 1942 when results came in from various marine research stations, showing that the Atlantic Ocean consisted of waters of varying temperature, density, salinity, habitat, and oxygen absorption.

Such occurs within a single ocean. What then of two different seas? Consider the Mediterranean and the Red Sea, or the Mediterranean and the Atlantic, or the Red Sea and the Gulf of Aden—they all meet at their specific straits.

In 1942, it became known for the first time that seas with varying traits and characteristics merge while maintaining their distinct differences. Even while seas ebb and flow, currents and waves carry water great distances, and hurricanes violently mix what they touch, each unique sea remains intact—as if they actually were separated by some barrier.

The Miracle

These verses speak about two adjacent saline seas, merging yet retaining their distinct characteristics, there being a barrier between them, barring one from truly mixing with the other.

Pearls and corals are mentioned in the same passage, indicating that the reference here is specific to bodies of salt water—since such things are only found therein.

Oceans and adjacent saline seas appear to the naked eye as if they are a single mass of water with unified properties. The truth is that they are a collective of bodies with varying values of salinity, temperature and density. This could not have been known without the use of modern technology, yet the Quran precisely mentioned the fact of the matter, explaining the merging and meeting of the seas, along with the barrier that restricts the breakdown of one water into another. Is not that a clear proof that the Quran is the Speech of Allaah.

Allaah The Almighty Says (what means): {This Quran is not such that it is contrived by anyone other than Allaah. But it is a confirmation of what was before it, and it details the Book—therein is no doubt—from the Lord of the worlds.} (Quran, 10:37)
