Fussilat, 45 Ayah
41:45
وَلَقَدۡ ءَاتَيۡنَا مُوسَى ٱلۡكِتَٰبَ فَٱخۡتُلِفَ فِيهِۚ وَلَوۡلَا كَلِمَةٞ سَبَقَتۡ مِن رَّبِّكَ لَقُضِيَ بَيۡنَهُمۡۚ وَإِنَّهُمۡ لَفِي شَكّٖ مِّنۡهُ مُرِيبٖ ٤٥
Wa Laqad 'Ātaynā Mūsá Al-Kitāba Fākhtulifa Fīhi ۗ Wa Lawlā Kalimatun Sabaqat Min Rabbika Laquđiya Baynahum ۚ Wa 'Innahum Lafī Shakkin Minhu Murībin
