النساۤء — An-Nisa' Ayat 82

اَفَلَا يَتَدَبَّرُوْنَ الْقُرْاٰنَ ۗ وَلَوْ كَانَ مِنْ عِنْدِ غَيْرِ اللّٰهِ لَوَجَدُوْا فِيْهِ اخْتِلَافًا كَثِيْرًا

Afalā yatadabbarūnal-qur'ān(a), wa lau kāna min ‘indi gairillāhi lawajadū fīhikhtilāfan kaṡīrā(n).

"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."
