Sweet and Salt
Scientists have studied the lower area of rivers near the sea. They found that this area has specific characteristicsm being moderate in salinity and density while at both ends we find a sweet river (palatable and sweet) and a sea with excess salinity (salt and bitter). And this downstream area is ecologically very sensitive and works on isolating the sea from the river otherwise the salty water would mix with fresh water and all rivers in the world would be spoiled.
Through this scientific fact, it is shown that the region that separates the sweet river from the salty sea is very important and it different characteristics than that of both waters (the sweet and the salty). Scientists have found also that it has specific creatures, such as certain fish, which live only in it.
The Koran talked about this grace (a barrier and a complete partition between them) which means the area forbidden from the tyranny of the sea and it is one of the miracles of the Holy Koran. Therefore, we have to thank God for this grace. God be He exalted says (meaning), “And it is He who has let free the two seas (kinds of water): one is palatable and sweet, and the other is salt and bitter; and He has set a barrier and a complete partition between them.” (Sura Al-Furqan, ayah 53)
