۞ لَتَجِدَنَّ أَشَدَّ ٱلنَّاسِ عَدَٰوَةًۭ لِّلَّذِينَ ءَامَنُوا۟ ٱلْيَهُودَ وَٱلَّذِينَ أَشْرَكُوا۟ ۖ وَلَتَجِدَنَّ أَقْرَبَهُم مَّوَدَّةًۭ لِّلَّذِينَ ءَامَنُوا۟ ٱلَّذِينَ قَالُوٓا۟ إِنَّا نَصَٰرَىٰ ۚ ذَٰلِكَ بِأَنَّ مِنْهُمْ قِسِّيسِينَ وَرُهْبَانًۭا وَأَنَّهُمْ لَا يَسْتَكْبِرُونَ
Thou wilt find the most vehement of mankind in hostility to those who believe (to be) the Jews and the idolaters. And thou wilt find the nearest of them in affection to those who believe (to be) those who say: Lo! We are Christians. That is because there are among them priests and monks, and because they are not proud.
Surah Al-Maaida(5:82)
