OCEANOLOGY | BARRIER BETWEEN SWEET AND SALT
“He has let free the two bodies of flowing water, meeting together: Between them is a Barrier which they do not transgress.” [Al-Qur’an 55:19-20]
In the Arabic text the word barzakh means a barrier or a partition. This barrier, however, is not a physical partition. The Arabic word maraja literally means ‘they both meet and mix with each other’. Early commentators of the Qur’an were unable to explain the two opposite meanings for the two bodies of water, i.e. they meet and mix, and at the same time there is a barrier between them. Modern Science has discovered that in the 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.1 Oceanologists are now in a better position to explain this verse. 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 andbecomes homogenized with the other water. In a way this barrier serves as a transitional homogenizing area for the two waters.

This phenomenon is also mentioned in the following verse of the Qur'an:
“And made a separating bar between the two bodies of flowing water?” [Al-Qur’an 27:61]
This phenomenon occurs in several places, including the divider between the Mediterranean and the Atlantic Ocean at Gibralter. A white bar can also be clearly seen at Cape Point, Cape Peninsula, South Africa where the Atlantic Ocean meets the Indian Ocean.
But when the Qur’an speaks about the divider between fresh and salt water, it mentions the existence of “a forbidding partition” with the barrier.
“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. [Al-Qur’an 25:53]
Modern science has discovered that in estuaries, where fresh (sweet) and salt water meet, the situation is somewhat different from that found in places where two salt water seas meet. It has been discovered that what distinguishes fresh water from salt water in estuaries is a “pycnocline zone with a marked density discontinuity separating the two layers.”1 This partition (zone of separation) has a salinity different from both the fresh water and the salt water.2
This phenomenon occurs in several places, including Egypt, where the river Nile flows into the Mediterranean Sea.
These scientific phenomena mentioned in the Qur’an was also confirmed by Dr. William Hay, a wellknown marine scientist and Professor of Geological Sciences at the University of Colorado, U.S.A.
