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

We gave the Scripture to Moses but disputes arose about it- if it were not for a decree that had already been issued from your Lord, they would already have been judged- and still they are doubtful and suspicious of it.
And indeed We gave Mûsâ (Moses) the Scripture, but dispute arose therein. And had it not been for a Word that went forth before from your Lord, (the torment would have overtaken them) and the matter would have been settled between them. But truly, they are in grave doubt thereto (i.e. about the Qur’ân). [Tafsir Al-Qurtubi].
