Quran 60:9

إِنَّمَا يَنۡہَٮٰكُمُ ٱللَّهُ عَنِ ٱلَّذِينَ قَـٰتَلُوكُمۡ فِى ٱلدِّينِ وَأَخۡرَجُوڪُم مِّن دِيَـٰرِكُمۡ وَظَـٰهَرُواْ عَلَىٰٓ إِخۡرَاجِكُمۡ أَن تَوَلَّوۡهُمۡ‌ۚ وَمَن يَتَوَلَّهُمۡ فَأُوْلَـٰٓٮِٕكَ هُمُ ٱلظَّـٰلِمُونَ ٩

ALLAH enjoins you only from befriending those who fight you because of religion, evict you from your homes, and band together with others to banish you. You shall not befriend them. Those who befriend them are the transgressors.
