Surah Al-Baqarah, Verse 176

ذَٰلِكَ بِأَنَّ ٱللَّهَ نَزَّلَ ٱلۡكِتَٰبَ بِٱلۡحَقِّۗ وَإِنَّ ٱلَّذِينَ ٱخۡتَلَفُواْ فِي ٱلۡكِتَٰبِ لَفِي شِقَاقِۭ بَعِيدٖ١٧٦

dhālika bi-anna l-laha nazzala l-kitāba bil-ḥaqi wa-inna alladhīna ikh'talafū fī l-kitābi lafī shiqāqin baʿīdin

That is [deserved by them] because Allāh has sent down the Book in truth. And indeed, those who differ over the Book are in extreme dissension.
