And, O my people! I ask you not for wealth in return for it; my reward is only with Allah and I am not going to drive away those who believe; surely they shall meet their Lord, but I consider you a people who are ignorant:

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.
