And this was Ad; they denied the communications of their Lord, and disobeyed His messengers and followed the bidding of every insolent opposer (of truth).

Allah is He Who raised the heavens without any pillars that you see, and He is firm in power and He made the sun and the moon subservient (to you); each one pursues its course to an appointed time; He regulates the affair, making clear the signs that you may be certain of meeting your Lord.
