Quran 4, An-Nisa (the Women) ⓘ

4:89They long that ye should disbelieve even as they disbelieve, that ye may be upon a level (with them). So choose not friends from them till they forsake their homes in the way of Allah; if they turn back (to enmity) then take them and kill them wherever ye find them, and choose no friend nor helper from among them,

وَدُّوا لَوْ تَكْفُرُونَ كَمَا كَفَرُوا فَتَكُونُونَ سَوَاءً فَلَا تَتَّخِذُوا مِنْهُمْ أَوْلِيَاءَ حَتَّى يُهَاجِرُوا فِي سَبِيلِ اللَّهِ فَإِنْ تَوَلَّوْا فَخُذُوهُمْ وَاقْتُلُوهُمْ حَيْثُ وَجَدْتُمُوهُمْ وَلَا تَتَّخِذُوا مِنْهُمْ وَلِيًّا وَلَا نَصِيرًا
