Quran 4:89 An-Nisa, ayah 89 of 176

وَدُّوا۟ لَوْ تَكْفُرُونَ كَمَا كَفَرُوا۟ فَتَكُونُونَ سَوَآءً ۖ فَلَا تَتَّخِذُوا۟ مِنْهُمْ أَوْلِيَآءَ حَتَّىٰ يُهَاجِرُوا۟ فِى سَبِيلِ ٱللَّهِ ۚ فَإِن تَوَلَّوْا۟ فَخُذُوهُمْ وَٱقْتُلُوهُمْ حَيْثُ وَجَدتُّمُوهُمْ ۖ وَلَا تَتَّخِذُوا۟ مِنْهُمْ وَلِيًّا وَلَا نَصِيرًا ۝٨٩

4:89 They 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,
