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 were every tree that is in the earth (made into) pens and the sea (to supply it with ink), with seven more seas to increase it, the words of Allah would not come to an end; surely Allah is Mighty, Wise.
