Sura al-ʿAnkabūt 29:48

وَمَا كُنتَ تَتْلُوا۟ مِن قَبْلِهِۦ مِن كِتَٰبٍ وَلَا تَخُطُّهُۥ بِيَمِينِكَ إِذًا لَّٱرْتَابَ ٱلْمُبْطِلُونَ

wa-mā kunta tatlū min qablihi min kitābin wa-lā ṭakhuṭṭuhu bi-yamīnika idhan la-irtāba l-mubṭilūna

And thou wast not (able) to recite a Book before this (Book came), nor art thou (able) to transcribe it with thy right hand: In that case, indeed, would the talkers of vanities have doubted.
