This article is about the theological concept in Islam. For the novel by Geraldine Brooks see People of the Book (novel).

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).
