Surah Fussilat (فصلت) Ayah 45 - Tafsir | TafsirHub
وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ فَٱخْتُلِفَ فِيهِ ۗ وَلَوْلَا كَلِمَةٌۭ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ ۚ وَإِنَّهُمْ لَفِى شَكٍّۢ مِّنْهُ مُرِيبٍۢ
"And We had already given Moses the Scripture, but it came under disagreement. And if not for a word that preceded from your Lord, it would have been concluded between them. And indeed they are, concerning the Qur'an, in disquieting doubt."
