۞ وَهُوَ الَّذِي مَرَجَ الْبَحْرَيْنِ هَٰذَا عَذْبٌ فُرَاتٌ وَهَٰذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْزَخًا وَحِجْرًا مَّحْجُورًا (53)
(25:53) And it is He, Who has let loose the two seas, one palatable and sweet, the other bitter and saltish, and there is a partition between them, which is an insurmountable barrier. *68
*68) This phenomenon has been perceived in many places in the sea and on the land that sweet water and bitter water has existed side by side. Turkish Admiral Syedi Ali Ra'is, in his book Mir 'at-al-Mamalik, written in the 16th century, has mentioned a place in the Persian Gulf, where springs of sweet waver exist under the bitter waters of the sea, where he could get drinking water for his fleet. The American Oil Company at first obtained water from the same springs in the Persian Gulf, before they dug up wells near Dhahran for supply of drinking water. Near Bahrain also there exist springs of sweet water at the sea bed from which people have been taking water until quite recently. Besides this apparent meaning which gives a rational proof of Allah's being the One and the only Lord of the universe, the verse contains a subtle suggestion as well: When Allah wills, He can raise up a righteous community from among a large wicked society just as He can cause springs of palatable and sweet water to gush out from under the salty waters of the sea.
