يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا الْيَهُودَ وَالنَّصَارَىٰ أَوْلِيَاءَ ۘ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۚ وَمَنْ يَتَوَلَّهُمْ مِنْكُمْ فَإِنَّهُ مِنْهُمْ ۗ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الظَّالِمِينَ 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.
