Surah 37. As-Saffat, Ayah 11

I.e., out of primitive substances existing in their elementary forms in and on the earth (see surah {23}, note [4]) - substances which are as nothing when compared with the complexity of "the heavens and the earth and all that is between them": hence, man's individual resurrection is as nothing when compared with the creation of the multiform universe.

 i.e., the angels, the sun, the moon, the stars, and the mountains.

 Their father Adam (ﷺ).

"Their": "they" are the doubters, the evil ones, the deniers of Allah's grace and mercy, who laugh at Revelation and disbelieve in a Hereafter. Are they more important or more difficult to create than the wonderful variety of beings in Allah's spacious Creation? Do they forget their own lowly state, as having been created from muddy clay?

Cf. vi. 2; vii. 12; xxxii. 7; etc.
