The Holy Qur’an, referred simply as the Qur’an, is the sacred scripture, text or book of Islam.
Although Muslims acknowledge other sacred texts or scriptures, particularly the Christian and Jewish doctrines, the Qur’an is uniquely different and should be noted for the fact that Muslims believe that the Qur’an is the unaltered word of God, which was reveled to Prophet Muhammad.
As recited in the Qur’an, “it [the Qur’an] is nonetheless timeless, the word of God, revealed word for word in the Arabic language through God’s final messenger… therefore uncreated; like God, whose speech it is [the Qur’an], it has always existed.”
