Verse 7

وَلَوْ نَزَّلْنَا عَلَيْكَ كِتَـٰبًا فِى قِرْطَاسٍ فَلَمَسُوهُ بِأَيْدِيهِمْ لَقَالَ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ هَـٰذَآ إِلَّا سِحْرٌ مُّبِينٌ

And even if We had sent down to you a book made of paper so that they could touch it with their own hands, indeed the unfaithful would have said this is clear magic.
