Allah is He Who created the heavens and the earth and sent down water from the clouds, then brought forth with it fruits as a sustenance for you, and He has made the ships subservient to you, that they might run their course in the sea by His command, and He has made the rivers subservient to you.

And He it is Who has made the sea subservient that you may eat fresh flesh from it and bring forth from it ornaments which you wear, and you see the ships cleaving through it, and that you might seek of His bounty and that you may give thanks.

Or like utter darkness in the deep sea: there covers it a wave above which is another wave, above which is a cloud, (layers of) utter darkness one above another; when he holds out his hand, he is almost unable to see it; and to whomsoever Allah does not give light, he has no light.

And the two seas are not alike: the one sweet, that subdues thirst by its excessive sweetness, pleasant to drink; and the other salt, that burns by its saltness; yet from each of them you eat fresh flesh and bring forth ornaments which you wear; and you see the ships cleave through it that you may seek of His bounty and that you may be grateful.
