۞ يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْا لَا تَتَّخِذُوا الْيَهُوْدَ وَالنَّصٰرٰٓى اَوْلِيَاۤءَ ۘ بَعْضُهُمْ اَوْلِيَاۤءُ بَعْضٍۗ وَمَنْ يَّتَوَلَّهُمْ مِّنْكُمْ فَاِنَّهٗ مِنْهُمْ ۗ اِنَّ اللّٰهَ لَا يَهْدِى الْقَوْمَ الظّٰلِمِيْنَ ( المائدة: ٥١ )
Yaaa aiyuhal lazeena aamanoo laa tattakhizul Yahooda wan nasaaraaa awliyaaa'; ba'duhum awliyaaa'u ba'd; wa mai yatawallahum minkum fa innahoo minhum; innal laaha laa yahdil qawmaz zaalimeen (al-Māʾidah 5:51)
O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you – then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people. (Al-Ma'idah  : 51)

O you who believe, do not take the Jews and the Christians for intimate friends. They are friends to each other. Whoever takes them as intimate friends is one of them. Surely, Allah does not take the unjust people to the right path.
