Surah An-Nisa' (The Women), Verse 76

اَلَّذِیْنَ اٰمَنُوْا یُقَاتِلُوْنَ فِیْ سَبِیْلِ اللّٰهِ وَالَّذِیْنَ كَفَرُوْا یُقَاتِلُوْنَ فِیْ سَبِیْلِ الطَّاغُوْتِ فَقَاتِلُوْۤا اَوْلِیَآءَ الشَّیْطٰنِ اِنَّ كَیْدَ الشَّیْطٰنِ كَانَ ضَعِیْفًا 

Allazeena aamanoo yuqaatiloona fee sabeelil laahi wallazeena kafaroo yuqaatiloona fee sabeelit Taaghoot faqaatiloo awliyaaa'ash Shaitaan; inna kaidash Shaitaani kaana da'eefa

“Those who believe fight in the cause of Allah, and those who reject Faith Fight in the cause of Evil: So fight ye against the friends of Satan: feeble indeed is the cunning of Satan.”
