AN NISAA' — Ayat 89

وَدُّواْ لَوْ تَكْفُرُونَ كَمَا كَفَرُواْ فَتَكُونُونَ سَوَاء فَلاَ تَتَّخِذُواْ مِنْهُمْ أَوْلِيَاء حَتَّىَ يُهَاجِرُواْ فِي سَبِيلِ اللّهِ فَإِن تَوَلَّوْاْ فَخُذُوهُمْ وَاقْتُلُوهُمْ حَيْثُ وَجَدتَّمُوهُمْ وَلاَ تَتَّخِذُواْ مِنْهُمْ وَلِيًّا وَلاَ نَصِيرًا

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 Allah . But if they turn away, then seize them and kill them wherever you find them and take not from among them any ally or helper.
