﴿ ۞ إِنَّ قَٰرُونَ كَانَ مِن قَوْمِ مُوسَىٰ فَبَغَىٰ عَلَيْهِمْ ۖ وَءَاتَيْنَٰهُ مِنَ ٱلْكُنُوزِ مَآ إِنَّ مَفَاتِحَهُۥ لَتَنُوٓأُ بِٱلْعُصْبَةِ أُو۟لِى ٱلْقُوَّةِ إِذْ قَالَ لَهُۥ قَوْمُهُۥ لَا تَفْرَحْ ۖ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْفَرِحِينَ ﴾

“[NOW,] BEHOLD, Qarun was one of the people of Moses; but he arrogantly exalted himself above them - simply because We had granted him such riches that his treasure-chests alone would surely have been too heavy a burden for a troop of ten men or even more. When [they perceived his arrogance,] his people said unto him: “Exult not [in thy wealth], for, verily, God does not love those who exult [in things vain]!”
