The Koranic scribes were strictly forbidden to write down the sayings (hadith) of Prophet Muhammad (salla Allahu alihi wa sallam) and so through the Prophet's wisdom there has never, ever been any confusion whatsoever as to that which belongs to the text of the Koran and that belonging to his sayings. In addition to the writing down of the Holy Koran, literally thousands of Companions learned to recite the entire Holy Koran by heart and taught it to the next generation.
