The KORAN is the holy book of ISLAM. The origin of the word “Koran” is not specifically known.  Experts guess that it means either to gather or tie together, or to recite.   Around the time of Muhammad, 615 -630, the book was said to have been written about the stories Muhammad told after talking with the Angel Gabriel who was sent by God with revelations for Muhammad.  Later, after his death, the new entries into the Koran were written about those who followed Muhammad and what he taught them.  Later entries made in the Koran were stories about memories by the people who lived in that time, about the talks that Muhammad had with God.  Many of these references were written by the Muslim people who had heard them in their younger years and wanted them to be remembered.  As they grew old and died their families wanted  an exact meaning of all the words in the Koran.  The language it was written in had no punctuation, and so scholars began work that goes on to this day, trying to interpret the exact meaning of all the holy words in this book.  Some scholars say that the book has been misread and mistranslated.  Here is a link that tells more about the work to find the true meaning of this book: http://www.corkscrew-balloon.com/02/03/1bkk/04b.html.
