An-Nisâ’ 4:89
وَدُّوا لَوْ تَكْفُرُونَ كَمَا كَفَرُوا فَتَكُونُونَ سَوَاءً ۖ فَلَا تَتَّخِذُوا مِنْهُمْ أَوْلِيَاءَ حَتَّىٰ يُهَاجِرُوا فِي سَبِيلِ اللَّهِ ۚ فَإِن تَوَلَّوْا فَخُذُوهُمْ وَاقْتُلُوهُمْ حَيْثُ وَجَدتُّمُوهُمْ ۖ وَلَا تَتَّخِذُوا مِنْهُمْ وَلِيًّا وَلَا نَصِيرًا ٨٩
Waddoo law takfuroona kama kafaroo fatakoonoona sawaan fala tattakhithoo minhum awliyaa hatta yuhajiroo fee sabeeli Allahi fain tawallaw fakhuthoohum waoqtuloohum haythu wajadtumoohum wala tattakhithoo minhum waliyyan wala naseeran
They wish that you should disbelieve as they disbelieve, and then you would be equal; therefore take not to yourselves friends of them, until they emigrate in the way of God; then, if they turn their backs, take them, and slay them wherever you find them; take not to yourselves any one of them as friend or helper (4:89)
