Surah Al-An'am — Ayah 7 (6:7)
وَلَوۡ نَزَّلۡنَا عَلَيۡكَ كِتَٰبٗا فِي قِرۡطَاسٖ فَلَمَسُوهُ بِأَيۡدِيهِمۡ لَقَالَ ٱلَّذِينَ كَفَرُوٓاْ إِنۡ هَٰذَآ إِلَّا سِحۡرٞ مُّبِينٞ ٧
English translation (Saheeh International)
And even if We had sent down to you, [O Muḥammad], a written scripture on a page and they touched it with their hands, the disbelievers would say, "This is not but obvious magic."
Brief commentary
If we had sent down to you, O Messenger, a book written on paper and they had seen it with their eyes, they would not have accepted it out of stubbornness and denial; and they would have said, ‘What you have brought is nothing more than clear magic; and we will never believe in it’.
