The Koran
Most religions have some kind of holy text on which the religious beliefs are based．For Christians this text is the Holy Bible; for Jews it is the Torah and for Muslims it is the Koran.
Muslims believe that the Koran(consist) of revelations from God to Muhammad during the years 610 to 632 when Muhammad died．These revelations were written down by those  were close to him during this time and for several years after his death．They were gathered into the text (know) as the Koran during the years 630 to 650.
The interpretation of the Koran has always been a difficult task, even for Islamic scholars．For example, the meanings of some words are determined by dots above the vowels(元音)．In ancient Arabic, however, very often these dots (omit)．As a result some letters looked identical．Thus, the meanings of these words depended in many cases  the memories of the men who had written them．Early Muslims had to try to get the exact meanings of the words these people died and it was too late.
Unlike the Bible, in which the events are provided in time order, there is no reference tothings occurred in the Koran．In any case, unlike the Bible, most the suras - sections - are composed of orders and warnings．Unlike in the Bible, there are very few stories in the Koran．
Muslims believe that by (recite) the book, they create a holy atmosphere, and there are many Muslims who have learned the Koran by heart.
