Even if he learned how to read and write, he would still need scribes. That is assuming that the Prophet learned how to read and write quickly. I am not sure where you're going with this type of questioning. The Glorious Quran's Text is Miraculous:
www.answering-christianity.com/ac20.htm#linksIt is totally irrelevant to the Miracle of the Glorious Quran's Text,
Numerical and Scientific Miracles whether the Prophet was illiterate or not. I personally don't really care. Can any of your infidels refute the Glorious Quran's Numerical and Scientific Miracles?
No one could:You could not have planned and wrote the Miraculous Text of the Quran. The 1000s of numerical and scientific Miracles, and the miracle of the Text Itself and
how Words are spelled in certain ways to correlate with certain timings or Numerical Miracle, 100% testify that the Book was indeed from Allah Almighty and none else. Even your best scribes of today would not have been able to preserve the Glorious Quran like this. The Quran has 1000s of these Miracles.
So instead of derailing your brain and salvation to Hell with rotten infidels' nonsense, try to see the Glorious Quran in Its own Miracle. Who really cares who was literate and illiterate back then.
