Qur'an 11:110

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

“And We had certainly given Moses the Scripture, but it came under disagreement. And if not for a word 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.”
