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