arrogance and boasting

لَا تَحْسَبَنَّ ٱلَّذِينَ يَفْرَحُونَ بِمَآ أَتَوا۟ وَّيُحِبُّونَ أَن يُحْمَدُوا۟ بِمَا لَمْ يَفْعَلُوا۟ فَلَا تَحْسَبَنَّهُم بِمَفَازَةٍ مِّنَ ٱلْعَذَابِ ۖ وَلَهُمْ عَذَابٌ أَلِيمٌ

And never think that those who rejoice in what they have perpetrated and like to be praised for what they did not do - never think them [to be] in safety from the punishment, and for them is a painful punishment.

يَقُولُ أَهْلَكْتُ مَالًا لُّبَدًا

He says, "I have spent wealth in abundance."
