wastefulness and extravagance

وَءَاتِ ذَا ٱلْقُرْبَىٰ حَقَّهُۥ وَٱلْمِسْكِينَ وَٱبْنَ ٱلسَّبِيلِ وَلَا تُبَذِّرْ تَبْذِيرًا

And give the relative his right, and [also] the poor and the traveler, and do not spend wastefully.

إِنَّ ٱلْمُبَذِّرِينَ كَانُوٓا۟ إِخْوَٰنَ ٱلشَّيَـٰطِينِ ۖ وَكَانَ ٱلشَّيْطَـٰنُ لِرَبِّهِۦ كَفُورًا

Indeed, the wasteful are brothers of the devils, and ever has Satan been to his Lord ungrateful.
