Al-Mumtahanah - 60:9

إِنَّمَا يَنْهَاكُمُ اللَّهُ عَنِ الَّذِينَ قَاتَلُوكُمْ فِي الدِّينِ وَأَخْرَجُوكُم مِّن دِيَارِكُمْ وَظَاهَرُوا عَلَى إِخْرَاجِكُمْ أَن تَوَلَّوْهُمْ وَمَن يَتَوَلَّهُمْ فَأُوْلَئِكَ هُمُ الظَّالِمُونَ
[60:9]
Allah only forbids you respecting those who made war upon you on account of (your) religion, and drove you forth from your homes and backed up (others) in your expulsion, that you make friends with them, and whoever makes friends with them, these are the unjust.
Allah only forbids you, with regard to those who fight you for (your) Faith, and drive you out of your homes, and support (others) in driving you out, from turning to them (for friendship and protection). It is such as turn to them (in these circumstances), that do wrong.
Allah forbiddeth you only those who warred against you on account of religion and have driven you out from your homes and helped to drive you out, that ye make friends of them. Whosoever maketh friends of them - (All) such are wrong-doers.
