maybe angel gabriel but not Muhammed, muhammed was illitarate he could not write his own name.
As'salamu Alaikum dear brother Dawud,
I don't believe that Prophet Muhammad was illiterate either. This again goes back to our history having
false information and conspiracies. I believe the Prophet was literate, at least after the Holy Quran began to be revealed to him. Ummi does also mean BEING COMPREHENSIVE or GRAND, and not just illiterate. The Holy Quran was called UMM AL KITAB (the GRAND BOOK; the ULTIMATE BOOK). Ummi is derived from Umm. And Umm also means mother.
I don't believe the Prophet didn't know how to read and write when the Holy Quran began to be revealed to him. I believe he knew well how to read and write, or at least he was taught so by Angel Gabriel when he started receiving the Holy Quran's Revelations, and learning how to document Its very Complex Text.
It takes far more than an illiterate person to truly Master the Holy Quran in Text and Recitation, and to perfectly preserve It.
Take care akhi,
Osama Abdallah
