اَفَلَا یَتَدَبَّرُوْنَ الْقُرْاٰنَ وَلَوْ كَانَ مِنْ عِنْدِ غَیْرِ اللّٰهِ لَوَجَدُوْا فِیْهِ اخْتِلَافًا كَثِیْرًا ۟

Afalaa yatadabbaroonal Qur'aan; wa law kaana min 'indi ghairil laahi la wajadoo fee ikhtilaafan kaseeraa

“Do they not consider the Qur'an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.”
