sky
in Edition Clear Qur'an by Talal Itani / Al-Baqara (The Cow)

2:19Or like a cloudburst from the sky, in which is darkness, and thunder, and lightning. They press their fingers into their ears from the thunderbolts, in fear of death. But God surrounds the disbelievers.

2:22He who made the earth a habitat for you, and the sky a structure, and sends water down from the sky, and brings out fruits thereby, as a sustenance for you. Therefore, do not assign rivals to God while you know.

2:164In the creation of the heavens and the earth; in the alternation of night and day; in the ships that sail the oceans for the benefit of mankind; in the water that God sends down from the sky, and revives the earth with it after it had died, and scatters in it all kinds of creatures; in the changing of the winds, and the clouds disposed between the sky and the earth; are signs for people who understand.
