Hud 11:110

وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَـٰبَ فَٱخْتُلِفَ فِيهِ ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِى شَكٍّ مِّنْهُ مُرِيبٍ

Walaqad ātaynā mūsā l-kitāba fa-ukh'tulifa fīhi walawlā kalimatun sabaqat min rabbika laquḍiya baynahum wa-innahum lafī shakkin min'hu murībin

And We had certainly given Moses the Scripture, but it came under disagreement. And if not for a word¹ that preceded from your Lord, it would have been judged between them. And indeed they are, concerning it [i.e., the Qur’ān], in disquieting doubt.
