Just a few ayats of the surah:
17. Do they not look at the camels, how they are created?
18. And at the heaven, how it is raised?
19. And at the mountains, how they are rooted (and fixed firm)?
20. And at the earth, how it is outspread?
21. So remind them (O Muhammad صلى الله عليه وسلم) – you are only one who reminds.
