Quran 41:45 Fussilat, ayah 45 of 54

وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَـٰبَ فَٱخْتُلِفَ فِيهِ ۗ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِى شَكٍّ مِّنْهُ مُرِيبٍ ۝٤٥

41:45 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.
