Quran 4, An-Nisa (the Women) ⓘ

4:76Those who believe do battle for the cause of Allah; and those who disbelieve do battle for the cause of idols. So fight the minions of the devil. Lo! the devil's strategy is ever weak.

الَّذِينَ آمَنُوا يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ وَالَّذِينَ كَفَرُوا يُقَاتِلُونَ فِي سَبِيلِ الطَّاغُوتِ فَقَاتِلُوا أَوْلِيَاءَ الشَّيْطَانِ إِنَّ كَيْدَ الشَّيْطَانِ كَانَ ضَعِيفًا

4:77Hast thou not seen those unto whom it was said: Withhold your hands, establish worship and pay the poordue, but when fighting was prescribed for them behold! a party of them fear mankind even as their fear of Allah or with greater fear, and say: Our Lord! Why hast Thou ordained fighting for us? If only Thou wouldst give us respite yet a while! Say (unto them, O Muhammad): The comfort of this world is scant; the Hereafter will be better for him who wardeth off (evil); and ye will not be wronged the down upon a date-stone.

أَلَمْ تَرَ إِلَى الَّذِينَ قِيلَ لَهُمْ كُفُّوا أَيْدِيَكُمْ وَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ فَلَمَّا كُتِبَ عَلَيْهِمُ الْقِتَالُ إِذَا فَرِيقٌ مِنْهُمْ يَخْشَوْنَ النَّاسَ كَخَشْيَةِ اللَّهِ أَوْ أَشَدَّ خَشْيَةً وَقَالُوا رَبَّنَا لِمَ كَتَبْتَ عَلَيْنَا الْقِتَالَ لَوْلَا أَخَّرْتَنَا إِلَى أَجَلٍ قَرِيبٍ قُلْ مَتَاعُ الدُّنْيَا قَلِيلٌ وَالْآخِرَةُ خَيْرٌ لِمَنِ اتَّقَى وَلَا تُظْلَمُونَ فَتِيلًا
