Quran 21.32-35
And we have made the sky a roof withheld (from them). Yet they turn away from its portents. And He it is Who created the night and the day, and the sun and the moon. They float, each in an orbit. We appointed immortality for no mortal before thee. What! if thou diest, can they be immortal! Every soul must taste of death, and We try you with evil and with good, for ordeal. And unto Us ye will be returned.
