Surah Al-Ma'idah, Verse 14

وَمِنَ ٱلَّذِينَ قَالُوٓاْ إِنَّا نَصَٰرَىٰٓ أَخَذۡنَا مِيثَٰقَهُمۡ فَنَسُواْ حَظّٗا مِّمَّا ذُكِّرُواْ بِهِۦ فَأَغۡرَيۡنَا بَيۡنَهُمُ ٱلۡعَدَاوَةَ وَٱلۡبَغۡضَآءَ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِۚ وَسَوۡفَ يُنَبِّئُهُمُ ٱللَّهُ بِمَا كَانُواْ يَصۡنَعُونَ١٤

And from those who say, "We are Christians" We took their covenant; but they forgot a portion of that of which they were reminded. So We caused among them animosity and hatred until the Day of Resurrection. And Allāh is going to inform them about what they used to do.
