Al-Isrâ’ 17:37

وَلَا تَمْشِ فِي الْأَرْضِ مَرَحًا ۖ إِنَّكَ لَن تَخْرِقَ الْأَرْضَ وَلَن تَبْلُغَ الْجِبَالَ طُولًا ٣٧

Wala tamshi fee alardi marahan innaka lan takhriqa alarda walan tablugha aljibala toolan

“And walk not in the earth exultant. Lo! thou canst not rend the earth, nor canst thou stretch to the height of the hills.” (17:37)

Allah forbids His servants to strut and walk in a boastful manner:

وَلاَ تَمْشِ فِى الاٌّرْضِ مَرَحًا

(And walk not on the earth with conceit and arrogance.) meaning, walking in boastful manner and acting proud, like those who are arrogant oppressors.

إِنَّكَ لَن تَخْرِقَ الاٌّرْضَ

(Verily, you can neither rend nor penetrate the earth) means, you cannot penetrate the earth with your walking. This was the opinion of Ibn Jarir.
