Lo! In the creation of the heavens and the earth, and the difference of night and day, and the ships which run upon the sea with that which is of use to men, and the water which Allah sendeth down from the sky, thereby reviving the earth after its death, and dispersing all kinds of beasts therein, and in the ordinance of the winds, and the clouds obedient between heaven and earth: are signs of Allah's Sovereignty for people who have sense.
