This remarkable book has been written by the
    Rev. W. St. Clair-Tisdall, Missionary, C.M.S., Julfa, Persia. It takes up a
    subject never as yet brought properly under discussion either by Muslims or
    Christians  namely, the origin of the Qur'an, and the Sources from which
    both it and Tradition have been derived. By the teaching of Muhammad the Qur'an
    is of divine origin, and was brought down, as Tradition tells us, word
    by word by Gabriel to the Prophet's ear. The original is "written
    on a Tablet, kept in Heaven,"1 "sent down on the night of al
    Cadr"2 by
    the Almighty. Thus the Qur'an comes from God alone, heavenly, divine, and
    uncreate from all eternity. Now if it be shown that much of this grand book
    can be traced to human Sources existing daily around the Prophet, then Islam
    falls to the ground. And this is what the Author proves with marvelous power
    and erudition.
