وَلَقَدْ آتَيْنَا مُوسَى الْكِتَابَ فَاخْتُلِفَ فِيهِ ۗ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِنْ رَبِّكَ لَقُضِيَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِي شَكٍّ مِنْهُ مُرِيبٍ

Surah Fussilat : 45
And We had already given Moses the Scripture, but it came under disagreement. And if not for a word that preceded from your Lord, it would have been concluded between them. And indeed they are, concerning the Qur'an, in disquieting doubt.
