﴿ وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ فَٱخْتُلِفَ فِيهِ ۚ وَلَوْلَا كَلِمَةٌۭ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِى شَكٍّۢ مِّنْهُ مُرِيبٍۢ ﴾

“And, indeed, [similar was the case when] We vouchsafed the divine writ unto Moses, and some of his people set their own views against it; and had it not been for a decree that had already gone forth from thy Sustainer, judgment would indeed have been passed on them [then and there]: for, behold, they were in grave doubt, amounting to suspicion, about him [who called them unto God].”
