وَدُّوا۟ لَوْ تَكْفُرُونَ كَمَا كَفَرُوا۟ فَتَكُونُونَ سَوَآءًۭ ۖ فَلَا تَتَّخِذُوا۟ مِنْهُمْ أَوْلِيَآءَ حَتَّىٰ يُهَاجِرُوا۟ فِى سَبِيلِ ٱللَّهِ ۚ فَإِن تَوَلَّوْا۟ فَخُذُوهُمْ وَٱقْتُلُوهُمْ حَيْثُ وَجَدتُّمُوهُمْ ۖ وَلَا تَتَّخِذُوا۟ مِنْهُمْ وَلِيًّۭا وَلَا نَصِيرًا
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,
Surah An-Nisaa(4:89)
