Arrogance and materialism

أَوْ يُصْبِحَ مَآؤُهَا غَوْرًا فَلَن تَسْتَطِيعَ لَهُۥ طَلَبًا

Or its water will become sunken [into the earth], so you would never be able to seek it."

وَٱبْتَغِ فِيمَآ ءَاتَىٰكَ ٱللَّهُ ٱلدَّارَ ٱلْـَٔاخِرَةَ ۖ وَلَا تَنسَ نَصِيبَكَ مِنَ ٱلدُّنْيَا ۖ وَأَحْسِن كَمَآ أَحْسَنَ ٱللَّهُ إِلَيْكَ ۖ وَلَا تَبْغِ ٱلْفَسَادَ فِى ٱلْأَرْضِ ۖ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْمُفْسِدِينَ

But seek, through that which Allāh has given you, the home of the Hereafter; and [yet], do not forget your share of the world. And do good as Allāh has done good to you. And desire not corruption in the land. Indeed, Allāh does not like corrupters."

يَحْسَبُ أَنَّ مَالَهُۥٓ أَخْلَدَهُۥ

He thinks that his wealth will make him immortal.
