Verily in the creation of the heavens and the earth, in the alternation of the night and the day, in the ships (and vessels) which sail through the ocean carrying cargo, profitable for the people, in the (rain) water which Allah pours down from the sky reviving therewith the earth to life after its death, (the earth) in which He has scattered animals of all kinds, and in the changing wind directions and in the clouds (that trail) between the sky and the earth, duty-bound (under Allah’s Command) — certainly, (in these) are (many) Signs (of Allah’s Power) for those who put their reason to work.
