Why vanity is wrong

۞ وَٱعْبُدُوا۟ ٱللَّهَ وَلَا تُشْرِكُوا۟ بِهِۦ شَيْـًۭٔا ۖ وَبِٱلْوَٰلِدَيْنِ إِحْسَٰنًۭا وَبِذِى ٱلْقُرْبَىٰ وَٱلْيَتَٰمَىٰ وَٱلْمَسَٰكِينِ وَٱلْجَارِ ذِى ٱلْقُرْبَىٰ وَٱلْجَارِ ٱلْجُنُبِ وَٱلصَّاحِبِ بِٱلْجَنۢبِ وَٱبْنِ ٱلسَّبِيلِ وَمَا مَلَكَتْ أَيْمَٰنُكُمْ ۗ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ مُخْتَالًۭا فَخُورًا

Serve Allah, and join not any partners with Him; and do good- to parents, kinsfolk, orphans, those in need, neighbours who are near, neighbours who are strangers, the companion by your side, the wayfarer (ye meet), and what your right hands possess: For Allah loveth not the arrogant, the vainglorious;-

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

Nor walk on the earth with insolence: for thou canst not rend the earth asunder, nor reach the mountains in height.

تِلْكَ ٱلدَّارُ ٱلْءَاخِرَةُ نَجْعَلُهَا لِلَّذِينَ لَا يُرِيدُونَ عُلُوًّۭا فِى ٱلْأَرْضِ وَلَا فَسَادًۭا ۚ وَٱلْعَٰقِبَةُ لِلْمُتَّقِينَ

That Home of the Hereafter We shall give to those who intend not high-handedness or mischief on earth: and the end is (best) for the righteous.

وَلَا تُصَعِّرْ خَدَّكَ لِلنَّاسِ وَلَا تَمْشِ فِى ٱلْأَرْضِ مَرَحًا ۖ إِنَّ ٱللَّهَ لَا يُحِبُّ كُلَّ مُخْتَالٍۢ فَخُورٍۢ

"And swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant boaster.

ذَٰلِكُم بِمَا كُنتُمْ تَفْرَحُونَ فِى ٱلْأَرْضِ بِغَيْرِ ٱلْحَقِّ وَبِمَا كُنتُمْ تَمْرَحُونَ

"That was because ye were wont to rejoice on the earth in things other than the Truth, and that ye were wont to be insolent.

لِّكَيْلَا تَأْسَوْا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا تَفْرَحُوا۟ بِمَآ ءَاتَىٰكُمْ ۗ وَٱللَّهُ لَا يُحِبُّ كُلَّ مُخْتَالٍۢ فَخُورٍ

In order that ye may not despair over matters that pass you by, nor exult over favours bestowed upon you. For Allah loveth not any vainglorious boaster,-
