Al-Hadid 57:23
لِّكَيْلَا تَأْسَوْا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا تَفْرَحُوا۟ بِمَآ ءَاتَىٰكُمْ ۗ وَٱللَّهُ لَا يُحِبُّ كُلَّ مُخْتَالٍ فَخُورٍ
Likayla ta/saw AAala mafatakum wala tafrahoo bima atakumwallahu la yuhibbu kulla mukhtalinfakhoor
"In order that you not despair over what has eluded you and not exult [in pride] over what He has given you. And Allāh does not like everyone self-deluded and boastful -"
Al-Hadid 57:23, translation by Sahih International
A short reflection
So that you do not grieve for what has eluded you, and not exult in what He has given you. Allah does not like every self-deluded boaster.
