مرج البحرين. 25vs53

Allah has portioned it out among His creatures according to their needs; rivers and springs in every land, according to what they need for themselves and their lands This was the view of Ibn Jurayj and of Ibn Jarir, and this is the meaning without a doubt, for nowhere in creation is there a sea which is fresh and sweet
and that is salty and bitter; meaning that it is salty, bitter and not easy to swallow Is there any god with Allah! meaning, between the sweet water and the saltwater

And it is He Who has let free the two seas, this is palatable and sweet, and that is salty and bitter; means, He has created the two kinds of water, sweet and salty.

Between them is a barrier which none of them can transgress
{ مَرَجَ ٱلْبَحْرَيْنِ يَلْتَقِيَانِ } * { بَيْنَهُمَا بَرْزَخٌ لاَّ يَبْغِيَانِ }
Allah, may He be glorified, the One Whose power is absolute, has set these laws in motion, so all of these seas are stationary, and He has made their water salty lest the air turn putrid because of them and the whole earth turn rotten as a result, and lest the earth spoil because of the animals dying on it
مرج البحرين يلتقيان أين يقع في أي دولة
The sweet water is that which flows amidst people
Nay, but most of them know not! Then which of the blessings of your Lord will you both deny! The sweet water is like that in rivers, springs and wells, which is fresh, sweet, palatable water Allah has told us about reality so that His servants may realize His blessings to them and give thanks to Him
At the beginning of each month the tides ebb and flood, and when the month starts to wane they retreat until they go back to where they started

When the crescent of the following month appears, the tide begins to ebb again until the fourteenth of the month, then it decreases.

تفسير قوله تعالى : ( مرج البحرين يلتقيان بينهما برزخ لا يبغيان )
This is like the seas that are known in the east and the west, the Atlantic Ocean and the Straits that lead to it, the Red Sea, the Arabian Sea, the Persian Gulf, the China Sea, the Indian Ocean, the Mediterranean Sea, the Black Sea and so on, all the seas that are stable and do not flow, but they swell and surge in the winter and when the winds are strong, and they have tides that ebb and flow
