For many centuries Muslims have been taught to believe that the Qur'an has been preserved in its
original Arabic text right from the time of Muhammad, the prophet of Islam, down to this very day
absolutely intact without changes, deletions or additions of any kind and with no variance in reading.
At the same time they have also been taught that this suggested textual perfection of the book proves
that the Qur'an must be the Word of God. No one but Allah, it is claimed, could have preserved the
text so well. This sentiment has become so strongly established in the Muslim world that one will
rarely find a Muslim scholar making a critical analysis of the early transmission of the text of the
Qur'an and, when such analyses do appear, they are predictably unwelcome.
