Did Mohammed write the Quran
It is factual mistake that Mohammed wrote the Quran. Shortly after Muhammad’s death, the Quran was gathered by his companions who wrote down and memorized parts of it. These notes had differences that motivated Kalif Uthman ibn Affan to establish a standard version now known as Uthman’s codex, which is generally regarded as the original of the Qur’an known today. This is known knowledge among Islamic scholars and professors at various universities.
Muslim scholars believe that Muhammad was the illiterate, as mentioned in the Qur’an itself: “Those who follow the Messenger, the Prophet, who can neither read nor write, as they will find described in the Torah and the Gospel (as is) with them …… “Quran 7: 157.
Some researchers, such as John Wansbrough, Michael Cook and Patricia Crone, have not been willing to award the entire Quran to Muhammad (or Uthman) and claim that “there is no evidence of the existence of the Quran in any form before the last decade of it 7th century. ”
What is at least correct is that the Quran was not recorded by Muhammad.
