﴿ وَلَا تَمْشِ فِى ٱلْأَرْضِ مَرَحًا ۖ إِنَّكَ لَن تَخْرِقَ ٱلْأَرْضَ وَلَن تَبْلُغَ ٱلْجِبَالَ طُولًۭا ﴾

“And walk not on earth with haughty self-conceit: for, verily, thou canst never rend the earth asunder, nor canst thou ever grow as tall as the mountains!”

Condemnation of strutting 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.
