Koran a tradycje religijne „ludzi Księgi”

A comparative study of the Qur'an proves a similarity in its contents with the earlier religious texts of the “People of the Book”, that means the Jews and the Christians. An analysis of these parallelisms shows also some differences between them and does not allow to consider the Qur'an as a simple compilation of earlier Scriptures. Muslims recognize that one Word of God is revealed in them by stages in different periods of humanity. God's truth contained in them has been corrupted, so that a new and perfect revelation was necessary, that of the Qur'an, to purify the previous Scriptures from falsehood. The belief in one God is the truth uniting all the revelations. No partners should be set up with Him, but everyone must bow to His Will. The purpose of the Qur'an is to show the hidden meaning of the ancient Scriptures, so that they become an instructive example for “men endued with understanding”. It is the belief in one God, the warning of punishment for the disbelievers and the announcement of the good news to the followers of the right path indicated by God in His final revelation.
