Surah An-Nisa 4:82

أَفَلَا يَتَدَبَّرُونَ ٱلْقُرْءَانَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ ٱللَّهِ لَوَجَدُوا۟ فِيهِ ٱخْتِلَـٰفًا كَثِيرًا

Then do they not reflect upon the Qur’ān? If it had been from [any] other than Allāh, they would have found within it much contradiction.

Translation: Saheeh International

Tafsir

What do they not ponder do they not contemplate the Qur’ān? and the marvellous truths contained in it. If it had been from other than God surely they would have found therein much inconsistency much contradiction in meaning and irregularity in arrangement.
