Surah 40. Ghafir, Ayah 57

I.e., of the universe as a whole. By stressing the fact that man is only a small, insignificant part of the universe, the Qur'an points out the absurdity of the man-centred world-view alluded to in the preceding verse.

The heavens and the earth include mankind and all other creatures and millions of stars. Man is himself but a tiny part of creation. Why should he be so ego-centric? The whole is greater than a tiny part of it. And Allah Who created the whole of the Worlds is able to do much more wonderful things than can enter the imagination of man. Why should man be arrogant and doubt the Resurrection, and take upon himself to doubt the possibility of Allah's Revelation? It is only because he has made himself blind. See next verse.
