In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Allaah [The Most High] said:
وَلَا تَمۡشِ فِى ٱلۡأَرۡضِ مَرَحًاۖ إِنَّكَ لَن تَخۡرِقَ ٱلۡأَرۡضَ وَلَن تَبۡلُغَ ٱلۡجِبَالَ طُولاً۬
”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”. [17:37]
Meaning: Do not be proud, haughty and arrogant; exalting yourself above the truth and the creation. Indeed, this action of yours can neither rend nor penetrate the earth, nor can you attain a stature like that of the mountains in height through your pride; rather you are debased in the Sight of Allaah and in the sight of the creation, hated and detested. Indeed, you have acquired the most evil and despicable of qualities, whilst not being able to achieve what you desire.
