37وَلَا تَمْشِ فِى ٱلْأَرْضِ مَرَحًا ۖ إِنَّكَ لَن تَخْرِقَ ٱلْأَرْضَ وَلَن تَبْلُغَ ٱلْجِبَالَ طُولًا
38كُلُّ ذَٰلِكَ كَانَ سَيِّئُهُۥ عِندَ رَبِّكَ مَكْرُوهًا
37. And walk not on the earth with conceit and arrogance. Verily, you can neither rend nor penetrate the earth nor can you attain a stature like the mountains in height. 38. All the bad aspects of these (the above mentioned things) are hateful to your Lord.
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.
