Surah Al-Mai'dah (The Spread Table), Verse 14

وَمِنَ الَّذِیْنَ قَالُوْۤا اِنَّا نَصٰرٰۤی اَخَذْنَا مِیْثَاقَهُمْ فَنَسُوْا حَظًّا مِّمَّا ذُكِّرُوْا بِهٖ فَاَغْرَیْنَا بَیْنَهُمُ الْعَدَاوَةَ وَالْبَغْضَآءَ اِلٰی یَوْمِ الْقِیٰمَةِ وَسَوْفَ یُنَبِّئُهُمُ اللّٰهُ بِمَا كَانُوْا یَصْنَعُوْنَ ۟

“From those, too, who call themselves Christians, We did take a covenant, but they forgot a good part of the message that was sent them: so we estranged them, with enmity and hatred between the one and the other, to the day of judgment. And soon will Allah show them what it is they have done.”
