No one with arrogance enters Paradise
لَا يَدْخُلُ الْجَنَّةَ مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ ذَرَّةٍ مِنْ كِبْرٍ
La yadkhulu-l-jannata man kana fi qalbihi mithqalu dharratin min kibr.
"No one with an atom's weight of arrogance in his heart will enter Paradise."
Narrated by Abdullah ibn Mas'ud. Sahih Muslim 91
A short reflection
The hadith clarifies: arrogance is rejecting truth and looking down on people. A small, routine audit to run on the heart.
