Quran Al-Baqarah 2:176

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

Translation

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.
