Those who believe fight in the cause of Allah, and those who disbelieve fight in the cause of Taghut. So fight against the allies of Satan. Indeed, the plot of Satan has ever been weak.
الَّذِينَ آمَنُوا يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ ۖ وَالَّذِينَ كَفَرُوا يُقَاتِلُونَ فِي سَبِيلِ الطَّاغُوتِ فَقَاتِلُوا أَوْلِيَاءَ الشَّيْطَانِ ۖ إِنَّ كَيْدَ الشَّيْطَانِ كَانَ ضَعِيفًا
