Worship God who has rendered the earth as a floor for you and the sky as a dome for you and has sent water down from the sky to produce fruits for your sustenance. Do not knowingly set up anything as an equal to God. [2:22]
The creation of the heavens and the earth, the alternation of nights and days, the ships that sail in the sea for the benefit of the people, the water that God sends from the sky to revive the dead earth where He has scattered all kinds of animals, the winds of all directions, and the clouds rendered for service between the sky and the earth are all evidence (of His existence) for those who use their reason. [2:164]
