أَعُوذُ بِاللهِ السَّمِيعِ الْعَلِيمِ مِنَ الشَّيْطَانِ الرَّجِيمِ مِنْ هَمْزَهِ وَنَفْخِهِ وَنَفْثِهِ
سورة الإسراء
وَلَا تَمْشِ فِي الْأَرْضِ مَرَحًا إِنَّكَ لَن تَخْرِقَ الْأَرْضَ وَلَن تَبْلُغَ الْجِبَالَ طُولًا ﴿٣٧﴾كُلُّ ذَٰلِكَ كَانَ سَيِّئُهُ عِندَ رَبِّكَ مَكْرُوهًا ﴿٣٨﴾
I seek refuge with Allah, the Hearing, the Knowing, from the cursed Satan, from his coercion, lures to arrogance and poems
Surah Al-Isra
And walk not in the earth exultant. Lo! thou canst not rend the earth, nor canst thou stretch to the height of the hills. (37) The evil of all that is hateful in the sight of thy Lord. (38) 17:37-38
Tafsir Ibn Kathir
أَعُوذُ بِاللهِ السَّمِيعِ الْعَلِيمِ مِنَ الشَّيْطَانِ الرَّجِيمِ
Condemnation of strutting
Allah forbids His servants to strut and walk in a boastful manner:
وَلاَ تَمْشِ فِي الأَرْضِ 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 الأَرْضَ ...
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.
... وَلَن تَبْلُغَ الْجِبَالَ طُولاً ﴿٣٧﴾
nor can you attain a stature like the mountains in height.
كُلُّ ذَلِكَ كَانَ سَيٍّئُهُ عِنْدَ رَبِّكَ مَكْرُوهًا ﴿٣٨﴾
All the bad aspects of these (the above mentioned things) are hateful to your Lord.
