Surah Al-Isra, Verse 36:
وَلَا تَقْفُ مَا لَيْسَ لَكَ بِهِ عِلْمٌ إِنَّ السَّمْعَ وَالْبَصَرَ وَالْفُؤَادَ كُلُّ أُولَٰئِكَ كَانَ عَنْهُ مَسْئُولًا

And follow not (O man i.e., say not, or do not or witness not, etc.) that of which you have no knowledge (e.g. one’s saying: “I have seen,” while in fact he has not seen, or “I have heard,” while he has not heard). Verily! The hearing, and the sight, and the heart, of each of those you will be questioned (by Allah).

Surah Al-Isra, Verse 37:
وَلَا تَمْشِ فِي الْأَرْضِ مَرَحًا إِنَّكَ لَن تَخْرِقَ الْأَرْضَ وَلَن تَبْلُغَ الْجِبَالَ طُولًا

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.

Surah Al-Isra, Verse 38:
كُلُّ ذَٰلِكَ كَانَ سَيِّئُهُ عِندَ رَبِّكَ مَكْرُوهًا

All the bad aspects of these (the above mentioned things) are hateful to your Lord.
