TWO RIVERS AND A BARRIER...

THE SEAS NOT MINGLING WITH ONE ANOTHER

One of the properties of seas that has only recently been discovered is related in a verse of the Qur'an as follows:

He has let loose the two seas, converging together, with a barrier between them they do not break through.

(Qur'an, 55:19-20)

This property of the seas, that is, that they meet and yet do not intermix, has only very recently been discovered by oceanographers. Because of the physical force called "surface tension," the waters of neighbouring seas do not mix. Caused by the difference in the density of their waters, surface tension prevents them from mingling with one another, just as if a thin wall were between them.

[Richard A. Davis, Principles of Oceanography (Don Mills, Ontario : Addison-Wesley Publishing Company), 92-93]

It is interesting that, during a period when there was little knowledge of physics, and of surface tension, or oceanography, this truth was revealed in the Qur'an.

There are large waves, strong currents, and tides in the Mediterranean Sea and the Atlantic Ocean . Mediterranean Sea water enters the Atlantic by Gibraltar . But their temperature, salinity, and densities do not change, because of the barrier that separates them. http://www.harunyah ya.com/miracles_ of_the_quran_ p1_07.php# 1

Below Shown Photos are of the two rivers flowing in southern part near Cape Town , South Africa .

These rivers flow together and there nature came to know in the starting of 20th century where as ALLAH (SWT)mentioned the nature of these two rivers in Holy Quran around 1400years Back.

These two river flow together and finally settle down in the Ocean,taste of one river is extreamly sweet whereas the taste of another river is extreamly opposite (that is bitter) but they never mix.There is nothing in between these rivers which stops them from mixing togther but its is the will & order of ALLAH (SWT)

SUBHANALLAH....
