وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ فَٱخْتُلِفَ فِيهِ ۗ وَلَوْلَا كَلِمَةٌۭ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِى شَكٍّۢ مِّنْهُ مُرِيبٍۢ
And We verily gave Moses the Scripture, but there hath been dispute concerning it; and but for a Word that had already gone forth from thy Lord, it would ere now have been judged between them; but lo! they are in hopeless doubt concerning it.
Surah Fussilat(41:45)
