Al Maidah, 51 Ayah
5:51
۞ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَتَّخِذُواْ ٱلۡيَهُودَ وَٱلنَّصَٰرَىٰٓ أَوۡلِيَآءَۘ بَعۡضُهُمۡ أَوۡلِيَآءُ بَعۡضٖۚ وَمَن يَتَوَلَّهُم مِّنكُمۡ فَإِنَّهُۥ مِنۡهُمۡۗ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ ٥١
Yā 'Ayyuhā Al-Ladhīna 'Āmanū Lā Tattakhidhū Al-Yahūda Wa An-Naşārá 'Awliyā'a ۘ Ba`đuhum 'Awliyā'u Ba`đin ۚ Wa Man Yatawallahum Minkum Fa'innahu Minhum ۗ 'Inna Al-Laha Lā Yahdī Al-Qawma Až-Žālimīna
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.
