Surah Al-Isra' (The Night Journey), Verse 27

اِنَّ الْمُبَذِّرِیْنَ كَانُوْۤا اِخْوَانَ الشَّیٰطِیْنِ وَكَانَ الشَّیْطٰنُ لِرَبِّهٖ كَفُوْرًا ۟

Innal mubazzireena kaanoo ikhwaanash shayaateeni wa kaanash shaytaanu li Rabbihee kafooraa

“Verily spendthrifts are brothers of the Evil Ones; and the Evil One is to his Lord (himself) ungrateful.”
