Nor are the two bodies of flowing water alike,- the one palatable, sweet, and pleasant to drink, and the other, salt and bitter. Yet from each (kind of water) do ye eat flesh fresh and tender, and ye extract ornaments to wear; and thou seest the ships therein that plough the waves, that ye may seek (thus) of the Bounty of Allah that ye may be grateful. (12)
Tafsir
There is a large store of water on the earth—salt water in the oceans and seas, and fresh water in rivers, lakes and springs. This water is the source of innumerable advantages for man. It is used for drinking and irrigation. The creatures which live in water provide valuable food for man. The oceans and seas, spread over three-fourths of the Earth enable transportation and form a vast storehouse of valuable objects like pearls, mineral ores, etc. God causes the earth to revolve around the sun and rotate on its axis in a regulated manner, thereby causing the seasons, and the alternation of day and night. There are similar innumerable arrangements which have been brought into being by the all-powerful God. As such, who else is there other than God who deserves man’s utmost gratitude? It is God with His unfathomable powers who can fulfill the needs of man, and not those imaginary gods who possess absolutely no powers.
