ذَٰلِكَ بِأَنَّ ٱللَّهَ نَزَّلَ ٱلۡكِتَٰبَ بِٱلۡحَقِّۗ وَإِنَّ ٱلَّذِينَ ٱخۡتَلَفُواْ فِي ٱلۡكِتَٰبِ لَفِي شِقَاقِۭ بَعِيدٖ ١٧٦
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.
Translation: Saheeh International (English)
Each word's meaning and sound
That punishment is what they get for hiding knowledge and guidance, because Allah revealed the sacred scriptures in truth, which must be made clear and not hidden. Also, those who disagree with the sacred scripture, believing some of it and hiding some of it, have taken a position that is far from the truth.
