And He it is Who merged the two seas letting them flow one adjacent to the other this one palatable sweet and the other saltish bitter; and He set between the two an isthmus so that the one does not mix with the other and a forbidding ban a shield that prevents the two from becoming mixed.
- 25:5353
۞ وَهُوَ الَّذِي مَرَجَ الْبَحْرَيْنِ هَٰذَا عَذْبٌ فُرَاتٌ وَهَٰذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْزَخًا وَحِجْرًا مَحْجُورًا
It is He who made two bodies of water flow side by side, one fresh (and) sweet, the other brine (and) bitter, and has placed an interstice, a barrier between them.
