164. The following are clear signs of the Oneness of Allah, glory be to Him, for those who understand the evidence and proof: the creation of the heavens and the earth, and the wonders in them; the succession of night and day; the passing of life and death; happiness and sorrow; wealth and poverty; ships that sail through the waters of the sea, carrying food, clothing, trade and other things that people need and which benefit them; water that Allah sends down, bringing the earth to life with the agriculture and pasture that grows in it, and the living creatures He spreads out in it; the changing of the winds from one direction to another; and the clouds, controlled between the sky and the earth.
