Quran 5, Al-Ma'ida (the Table spread) ⓘ

5:14And with those who say: "Lo! we are Christians," We made a covenant, but they forgot a part of that whereof they were admonished. Therefor We have stirred up enmity and hatred among them till the Day of Resurrection, when Allah will inform them of their handiwork.

وَمِنَ الَّذِينَ قَالُوا إِنَّا نَصَارَى أَخَذْنَا مِيثَاقَهُمْ فَنَسُوا حَظًّا مِمَّا ذُكِّرُوا بِهِ فَأَغْرَيْنَا بَيْنَهُمُ الْعَدَاوَةَ وَالْبَغْضَاءَ إِلَى يَوْمِ الْقِيَامَةِ وَسَوْفَ يُنَبِّئُهُمُ اللَّهُ بِمَا كَانُوا يَصْنَعُونَ
