Was Prophet صلى الله عليه وسلم Illiterate?
Also, it is claimed that as American habt reading and writing would be very likely.
The verse you mentioned talk about earliear books not Quran. The history tells us that when surah iqrah ayahs were revealed, Prophet Mohammad Saw said he didnt know how to read. Also. There were Katibs to write Quran. In Bible, it was also mentioned that unlettered prophet will come who will speak words of God (Dont remember reference) I will say Prophet Mohammad saw can not read or write.
