Most surely in the creation of the heavens and the earth and the alternation of the night and the day, and the ships that run in the sea with that which profits men, and the water that Allah sends down from the cloud, then gives life with it to the earth after its death and spreads in it all (kinds of) animals, and the changing of the winds and the clouds made subservient between the heaven and the earth, there are signs for a people who understand.

And with Him are the keys of the unseen treasures-- none knows them but He; and He knows what is in the land and the sea, and there falls not a leaf but He knows it, nor a grain in the darkness of the earth, nor anything green nor dry but (it is all) in a clear book.

So when they had reached the junction of the two (rivers) they forgot their fish, and it took its way into the sea, going away.

And He it is Who has made two seas to flow freely, the one sweet that subdues thirst by its sweetness, and the other salt that burns by its saltness; and between the two He has made a barrier and inviolable obstruction.

Or, Who made the earth a restingplace, and made in it rivers, and raised on it mountains and placed between the two seas a barrier. Is there a god with Allah? Nay! most of them do not know!

Or, Who guides you in utter darkness of the land and the sea, and Who sends the winds as good news before His mercy. Is there a god with Allah? Exalted by Allah above what they associate (with Him).
