Surah Al-Isra — Ayah 27 (17:27)
إِنَّ ٱلۡمُبَذِّرِينَ كَانُوٓاْ إِخۡوَٰنَ ٱلشَّيَٰطِينِۖ وَكَانَ ٱلشَّيۡطَٰنُ لِرَبِّهِۦ كَفُورٗا ٢٧
English translation (Saheeh International)
Indeed, the wasteful are brothers of the devils, and ever has Satan been to his Lord ungrateful.
Brief commentary
Those who spend their wealth in sin and those who are wasteful in their spending are the brothers of the devils, they follow their instructions of being wasteful and extravagant Satan is ever ungrateful towards His Lord, and he only does things that are sinful and only instructs that which displeases His Lord.
