Quran's factual origins

Just as I have come to know that the Bible is a translation of several books written by different authors, decades after the events which they purport to describe by non-eyewitnesses whose stories were transmitted by hearsay in the intervening decades, I am interested to know what real history has to say about the formation of the "holy" book known as the Qu'ran.

L'Orientalist now has 2 videos with information pertaining to the topic and here they're.
