An Nisa, 82 Ayah
4:82
أَفَلَا يَتَدَبَّرُونَ ٱلۡقُرۡءَانَۚ وَلَوۡ كَانَ مِنۡ عِندِ غَيۡرِ ٱللَّهِ لَوَجَدُواْ فِيهِ ٱخۡتِلَٰفٗا كَثِيرٗا ٨٢
'Afalā Yatadabbarūna Al-Qur'āna ۚ Wa Law Kāna Min `Indi Ghayri Al-Lahi Lawajadū Fīhi Akhtilāfāan Kathīrāan
Then do they not reflect upon the Qur'an? If it had been from [any] other than Allah, they would have found within it much contradiction.
