People of the Book ( ′Ahl al-Kitāb) are adherents of Abrahamic religions that predate Islam.
In Islam, the Qur'an is taken to represent the completion of these scriptures, and to synthesize them as God's true, final, and eternal message to humanity. Because the People of the Book recognize the God of Abraham, YHWH (יהוה) as the one and only god, as do Muslims, and they practice revealed faiths based on divine ordinances, tolerance and autonomy is accorded to them in societies governed by sharia (Islamic divine law).
In Judaism the term "People of the Book" ( Hebrew: עם הספר, Am HaSefer) is used to refer specifically to the Jewish people and the Torah, and to the Jewish people and the wider canon of written Jewish law (including the Mishnah and the Talmud). Adherents of other Abrahamic religions, which arose later than Judaism, are not included. As such, the designation is accepted by Jews as a reference to an identity rooted fundamentally in the Torah.
In Christianity, the Catholic Church rejects the similar expression "religion of the book" as a description of the Christian faith, preferring the term "religion of the Word of God", since the faith of Christ, according to Catholic teaching, is not found solely in the Christian Scriptures, but also in the Sacred Tradition and Magisterium of the Church. Nevertheless, other denominations, such as the Baptists, Methodists, Seventh-day Adventist Church, as well as Puritans and Shakers, have embraced the term "People of the Book".
People of the Book is a 2008 historical fiction novel by Geraldine Brooks. The story focuses on imagined events surrounding protagonist and real historical past of the still extant Sarajevo Haggadah, one of the oldest surviving Jewish illuminated texts.
