1. 4:36 وَٱعْبُدُوا۟ ٱللَّهَ وَلَا تُشْرِكُوا۟ بِهِۦ شَيْـًٔا وَبِٱلْوَٰلِدَيْنِ إِحْسَٰنًا وَبِذِى ٱلْقُرْبَىٰ وَٱلْيَتَٰمَىٰ وَٱلْمَسَٰكِينِ وَٱلْجَارِ ذِى ٱلْقُرْبَىٰ وَٱلْجَارِ ٱلْجُنُبِ وَٱلصَّاحِبِ بِٱلْجَنۢبِ وَٱبْنِ ٱلسَّبِيلِ وَمَا مَلَكَتْ أَيْمَٰنُكُمْ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ مُخْتَالًا فَخُورًا

   And serve Allah and do not associate any thing with Him and be good to the parents and to the near of kin and the orphans and the needy and the neighbor of (your) kin and the alien neighbor, and the companion in a journey and the wayfarer and those whom your right hands possess; surely Allah does not love him who is proud, boastful;
   

2. 11:10 وَلَئِنْ أَذَقْنَٰهُ نَعْمَآءَ بَعْدَ ضَرَّآءَ مَسَّتْهُ لَيَقُولَنَّ ذَهَبَ ٱلسَّيِّـَٔاتُ عَنِّىٓ إِنَّهُۥ لَفَرِحٌ فَخُورٌ

   And if We make him taste a favor after distress has afflicted him, he will certainly say: The evils are gone away from me. Most surely he is exulting, boasting;
   

3. 31:18 وَلَا تُصَعِّرْ خَدَّكَ لِلنَّاسِ وَلَا تَمْشِ فِى ٱلْأَرْضِ مَرَحًا إِنَّ ٱللَّهَ لَا يُحِبُّ كُلَّ مُخْتَالٍ فَخُورٍ

   And do not turn your face away from people in contempt, nor go about in the land exulting overmuch; surely Allah does not love any self-conceited boaster;
   

4. 55:14 خَلَقَ ٱلْإِنسَٰنَ مِن صَلْصَٰلٍ كَٱلْفَخَّارِ

   He created man from dry clay like earthen vessels,
   

5. 57:20 ٱعْلَمُوٓا۟ أَنَّمَا ٱلْحَيَوٰةُ ٱلدُّنْيَا لَعِبٌ وَلَهْوٌ وَزِينَةٌ وَتَفَاخُرٌۢ بَيْنَكُمْ وَتَكَاثُرٌ فِى ٱلْأَمْوَٰلِ وَٱلْأَوْلَٰدِ كَمَثَلِ غَيْثٍ أَعْجَبَ ٱلْكُفَّارَ نَبَاتُهُۥ ثُمَّ يَهِيجُ فَتَرَىٰهُ مُصْفَرًّا ثُمَّ يَكُونُ حُطَٰمًا وَفِى ٱلْءَاخِرَةِ عَذَابٌ شَدِيدٌ وَمَغْفِرَةٌ مِّنَ ٱللَّهِ وَرِضْوَٰنٌ وَمَا ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا مَتَٰعُ ٱلْغُرُورِ

   Know that this world's life is only sport and play and gaiety and boasting among yourselves, and a vying in the multiplication of wealth and children, like the rain, whose causing the vegetation to grow, pleases the husbandmen, then it withers away so that you will see it become yellow, then it becomes dried up and broken down; and in the hereafter is a severe chastisement and (also) forgiveness from Allah and (His) pleasure; and this world's life is naught but means of deception.
   

6. 57:23 لِّكَيْلَا تَأْسَوْا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا تَفْرَحُوا۟ بِمَآ ءَاتَىٰكُمْ وَٱللَّهُ لَا يُحِبُّ كُلَّ مُخْتَالٍ فَخُورٍ

   So that you may not grieve for what has escaped you, nor be exultant at what He has given you; and Allah does not love any arrogant boaster:
