Surah Al-An'am (The Cattle), Verse 7

وَلَوْ نَزَّلْنَا عَلَیْكَ كِتٰبًا فِیْ قِرْطَاسٍ فَلَمَسُوْهُ بِاَیْدِیْهِمْ لَقَالَ الَّذِیْنَ كَفَرُوْۤا اِنْ هٰذَاۤ اِلَّا سِحْرٌ مُّبِیْنٌ ۟

Wa law nazzalnaa 'alaika Kitaaban fee qirtaasin falamasoohu bi aideehim laqaalal lazeena kafarooo in haazaaa illaa sihrum mubeen

“If We had sent unto thee a written (message) on parchment, so that they could touch it with their hands, the Unbelievers would have been sure to say: "This is nothing but obvious magic!"”
