﴿ ذَٰلِكَ بِأَنَّ ٱللَّهَ نَزَّلَ ٱلْكِتَٰبَ بِٱلْحَقِّ ۗ وَإِنَّ ٱلَّذِينَ ٱخْتَلَفُوا۟ فِى ٱلْكِتَٰبِ لَفِى شِقَاقٍۭ بَعِيدٍۢ ﴾

“Thus it is: since it is God who bestows the divine writ from on high, setting forth the truth, all those who set their own views against the divine writ are, verily, most deeply in the wrong.”

That is because God has revealed the Book with the truth; and those that are at variance regarding the Book are in schism, far removed.]
