Question

And We had already given Moses the Scripture, but it came under disagreement.[1399] And if not for a word [i.e., decree][1400] that preceded from your Lord, it would have been concluded between them. And indeed they are, concerning it [i.e., the Qur’ān], in disquieting doubt. وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ فَٱخْتُلِفَ فِيهِ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ وَإِنَّهُمْ لَفِى شَكٍّ مِّنْهُ مُرِيبٍ 45

Accepted Answer

[1399] An alternative meaning is ''he was opposed over it.''[1400] See footnote to 10:19. Fussilat Part 24
