Quran 5:14 from Surah Al-Maaida on Divine Marvels.
وَمِنَ ٱلَّذِينَ قَالُوٓاْ إِنَّا نَصَٰرَىٰٓ أَخَذۡنَا مِيثَٰقَهُمۡ فَنَسُواْ حَظّٗا مِّمَّا ذُكِّرُواْ بِهِۦ فَأَغۡرَيۡنَا بَيۡنَهُمُ ٱلۡعَدَاوَةَ وَٱلۡبَغۡضَآءَ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِۚ وَسَوۡفَ يُنَبِّئُهُمُ ٱللَّهُ بِمَا كَانُواْ يَصۡنَعُونَ
English translation: And from those who said Indeed we (are) Christians We took their covenant but they forgot a part of what they were reminded of [it] So We aroused between them [the] enmity and [the] hatred till (the) Day (of) the Resurrection And soon will inform them Allah of what they used to do
