وَمِنَ الَّذِيْنَ قَالُوْٓا اِنَّا نَصٰرٰٓى اَخَذْنَا مِيْثَاقَهُمْ فَنَسُوْا حَظًّا مِّمَّا ذُكِّرُوْا بِهٖۖ فَاَغْرَيْنَا بَيْنَهُمُ الْعَدَاوَةَ وَالْبَغْضَاۤءَ اِلٰى يَوْمِ الْقِيٰمَةِ ۗ وَسَوْفَ يُنَبِّئُهُمُ اللّٰهُ بِمَا كَانُوْا يَصْنَعُوْنَ ( المائدة: ١٤ )

Sahih International:
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. (Al-Ma'idah [5] : 14)
1 Mufti Taqi Usmani
And from those who say, “We are Christians,” We took a pledge. So, they have overlooked a good deal of the Advice they were given. So, We had them stuck with enmity and malice among them right through the Day of Doom, and (then) Allah will tell them what they were doing.
