The Prophet ﷺ said: Allah Most High says: Pride is my cloak and majesty is my lower garment, and I shall throw him who view with me regarding one of them into Hell.  

قَالَ رَسُولُ اللَّهِ ﷺ قَالَ اللَّهُ ﷻ الْكِبْرِيَاءُ رِدَائِي وَالْعَظَمَةُ إِزَارِي فَمَنْ نَازَعَنِي وَاحِدًا مِنْهُمَا قَذَفْتُهُ فِي النَّارِ  

The Messenger of Allah ﷺ as saying: He who has in his heart as much pride as much pride as grain of mustard-seed will not enter paradise. And he who has in his heart as much faith as grain of mustard-seed will not enter Hell. Abu Dawud said: Al-Qasmali has transmitted it from Al-A'mash in a similar way.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَدْخُلُ الْجَنَّةَ مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ حَبَّةٍ مِنْ خَرْدَلٍ مِنْ كِبْرٍ وَلاَ يَدْخُلُ النَّارَ مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ خَرْدَلَةٍ مِنْ إِيمَانٍ  

A man who was beautiful came to the Prophet ﷺ. He said: Messenger of Allah, I am a man who likes beauty, and I have been given some of it, as you see. And I do not like that anyone excels me (in respect of beauty). Perhaps he said: "even to the extent of thong of my sandal (shirak na'li)", or he he said: "to the extent of strap of my sandal (shis'i na'li)". Is it pride? He replied: No, pride is disdaining what is true and despising people.  

أَنَّ رَجُلاً أَتَى النَّبِيَّ ﷺ وَكَانَ رَجُلاً جَمِيلاً فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي رَجُلٌ حُبِّبَ إِلَىَّ الْجَمَالُ وَأُعْطِيتُ مِنْهُ مَا تَرَى حَتَّى مَا أُحِبُّ أَنْ يَفُوقَنِي أَحَدٌ إِمَّا قَالَ بِشِرَاكِ نَعْلِي وَإِمَّا قَالَ بِشِسْعِ نَعْلِي أَفَمِنَ الْكِبْرِ ذَلِكَ قَالَ لاَ وَلَكِنَّ الْكِبْرَ مَنْ بَطَرَ الْحَقَّ وَغَمَطَ النَّاسَ
