Surah An-Nisa, ayah 89

4:89

وَدُّواْ لَوۡ تَكۡفُرُونَ كَمَا كَفَرُواْ فَتَكُونُونَ سَوَآءٗۖ فَلَا تَتَّخِذُواْ مِنۡهُمۡ أَوۡلِيَآءَ حَتَّىٰ يُهَاجِرُواْ فِي سَبِيلِ ٱللَّهِۚ فَإِن تَوَلَّوۡاْ فَخُذُوهُمۡ وَٱقۡتُلُوهُمۡ حَيۡثُ وَجَدتُّمُوهُمۡۖ وَلَا تَتَّخِذُواْ مِنۡهُمۡ وَلِيّٗا وَلَا نَصِيرًا ٨٩

Waddū law takfurūna kamā kafarū fatakūnūna sawā'an falā tattakhidhū minhum awliyā'a hattā yuhājirū fī sabīlillāhi fa in tawallaw fakhudhūhum waqtulūhum haythu wajattumūhum walā tattakhidhū minhum waliyyan walā nasīrā

They wish you would disbelieve as they disbelieved so you would be alike. So do not take from among them allies until they emigrate for the cause of Allāh. But if they turn away [i.e., refuse], then seize them and kill them [for their betrayal] wherever you find them and take not from among them any ally or helper,
