Fussilat - 41:45

وَلَقَدْ آتَيْنَا مُوسَى الْكِتَابَ فَاخْتُلِفَ فِيهِ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَقُضِيَ بَيْنَهُمْ وَإِنَّهُمْ لَفِي شَكٍّ مِّنْهُ مُرِيبٍ
[41:45]
And certainly We gave the Book to Musa, but it has been differed about, and had not a word already gone forth from your Lord, judgment would certainly have been given between them; and most surely they are in a disquieting doubt about it.
We certainly gave Moses the Book aforetime: but disputes arose therein. Had it not been for a Word that went forth before from thy Lord, (their differences) would have been settled between them: but they remained in suspicious disquieting doubt thereon.
And We verily gave Moses the Scripture, but there hath been dispute concerning it; and but for a Word that had already gone forth from thy Lord, it would ere now have been judged between them; but lo! they are in hopeless doubt concerning it.
