Dr. Mustafa Khattab, the Clear Quran - Surah Al-'Ankabut, ayah 48

Translation of Surah Al-'Ankabut, ayah 48 (29:48)

وَمَا كُنتَ تَتۡلُواْ مِن قَبۡلِهِۦ مِن كِتَٰبٖ وَلَا تَخُطُّهُۥ بِيَمِينِكَۖ إِذٗا لَّٱرۡتَابَ ٱلۡمُبۡطِلُونَ ٤٨
You ˹O Prophet˺ could not read any writing ˹even˺ before this ˹revelation˺, nor could you write at all. Otherwise, the people of falsehood would have been suspicious.
