Surah Al-Isra, Verse 27

إِنَّ ٱلۡمُبَذِّرِينَ كَانُوٓاْ إِخۡوَٰنَ ٱلشَّيَٰطِينِۖ وَكَانَ ٱلشَّيۡطَٰنُ لِرَبِّهِۦ كَفُورٗا٢٧

inna l-mubadhirīna kānū ikh'wāna l-shayāṭīni wakāna l-shayṭānu lirabbihi kafūran

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