AL MAA-IDAH — Ayat 14

وَمِنَ الَّذِينَ قَالُواْ إِنَّا نَصَارَى أَخَذْنَا مِيثَاقَهُمْ فَنَسُواْ حَظًّا مِّمَّا ذُكِّرُواْ بِهِ فَأَغْرَيْنَا بَيْنَهُمُ الْعَدَاوَةَ وَالْبَغْضَاء إِلَى يَوْمِ الْقِيَامَةِ وَسَوْفَ يُنَبِّئُهُمُ اللّهُ بِمَا كَانُواْ يَصْنَعُونَ

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 Allah is going to inform them about what they used to do.
