Quran 11:110 Hud, ayah 110 of 123

وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَـٰبَ فَٱخْتُلِفَ فِيهِ ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِى شَكٍّ مِّنْهُ مُرِيبٍ ۝١١٠

11:110 And we verily gave unto Moses the Scripture, and there was strife thereupon; and had it not been for a Word that had already gone forth from thy Lord, the case would have been judged between them, and lo! they are in grave doubt concerning it.
