Modern Science has discovered that in places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity and density.
Oceanographists are now in a better position to explain these concepts that there is a slanted unseen water barrier between the two seas through which water from one sea passes to the other. But when the water from one sea enters the other sea, it loses its distinctive characteristic and becomes homogenized with the other water. In a way, this barrier serves as a transitional homogenizing area for the two waters.
The Glorious Quran, as a divine book of scientific wisdom, explains about 1400 years ago the scientific concept of the barrier that:
“He has let free the two seas meeting together. Between them is a barrier which they do not trangress ” – (Quran 55:19-20).
The Quran mentions this phenomenon which occurs in several places, including the divider between the Mediterranean and the Atlantic Ocean at Gilbralter also in the following verse:
“And made a separating bar between the two seas (can there be another)” – (Quran 27:61).
Again, the Glorious Quran speaks about the divider between fresh and salt water, it mentions the existence of ‘a forbidding partition’ with the barrier in the verse:
“It is He (Allah) who has let free the two bodies of flowing water: one palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is not to be passed ” – (Quran 25:53).
These scientific phenomenon mentioned in the Quran was also confirmed by Dr William Hay who is a well-known Marine Scientist and Professor of Geological Sciences at the University of Colorado, USA. It, therefore, follows the instruction of Quran that:
“If ye realize this not, ask of those who possess the Message” – (Quran 16:43).
