The Qur'an is the literal word of
God, which He revealed to his Prophet Muhammad {صلى الله عليه وسلم}
through the Angel Gabriel. It was memorized by Muhammad {صلى الله عليه
وسلم} who then dictated it to his companions.
They, in turn, memorized
it, wrote it down, and reviewed it with the prophet Muhammad {صلى الله
عليه وسلم} moreover; the prophet Muhammad [صلى الله عليه وسلم] reviewed
the Qur'an with the Angel Gabriel once each year and twice in the last
year of his life. From the time the Qur'an was revealed, until this
day, there has always been a huge number of Muslims who have memorized
all of the Qur'an, letter by letter.
Some of them have even been able
to memorize all of the Qur'an by the age of ten. Not one letter of the
Qur'an has been changed over the centuries. The Quran which was
revealed fourteen centuries ago mentioned facts only recently
discovered or proven by scientists. This proves without doubt that the
Qur'an must be the literal word of God.
