Surah Al-Maaida Verse 51

۞ يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا الْيَهُودَ وَالنَّصَارَىٰ أَوْلِيَاءَ ۘ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۚ وَمَن يَتَوَلَّهُم مِّنكُمْ فَإِنَّهُ مِنْهُمْ ۗ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الظَّالِمِينَ

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

Translation / The Meaning

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.
