In the creation of the heavens and the earth; In the alternation of the night and the day; In the sailing of ships through the ocean, for the profit of mankind; In the rain which Allah sends down from the skies, And the life He gives to an earth that is dead; In the beasts of all kinds that He scatters through the earth; In the change of the winds, and the clouds. Indeed are Signs for a people that are wise" [2:164]
