Sura al-Māʾidah 5:14

وَمِنَ ٱلَّذِينَ قَالُوٓا۟ إِنَّا نَصَٰرَىٰٓ أَخَذْنَا مِيثَٰقَهُمْ فَنَسُوا۟ حَظًّا مِّمَّا ذُكِّرُوا۟ بِهِۦ فَأَغْرَيْنَا بَيْنَهُمُ ٱلْعَدَاوَةَ وَٱلْبَغْضَآءَ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ وَسَوْفَ يُنَبِّئُهُمُ ٱللَّـهُ بِمَا كَانُوا۟ يَصْنَعُونَ

wa-mina lladhīna qālū innā naṣāra akhadhnā mīthāqahum fa-nasū ḥaẓẓan mimmā dhukkirū bihi fa-aghraynā baynahumu l-ʿadāwata wa-l-baghḍāʾa ilā yawmi l-qiyāmati wa-sawfa yunabbiʾuhumu allāhu bi-mā kānū yaṣnaʿūna

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.
