The term People of the Book (Hebrew: עַם הַסֵּפֶר, Am HaSefer; Arabic: أهل الكتاب, Ahl al-Kitab; Persian: اهل کتاب, Ahl-e Ketab) refers to those religions that are of revealed scriptures, most commonly referring to Judaism, Christianity, and Islam. The phrase originates from the Quran, where it is used to describe Jews, Christians, and Sabians as "People of the Book" because they possess revealed scriptures. In a broader sense, the term can also include other religions with sacred texts, such as Zoroastrianism, the Baháʼí Faith, and the Druze faith. The concept highlights the shared heritage and theological foundations among these religions, emphasizing their common roots and mutual recognition of divine revelation through scripture. This recognition has historically influenced interfaith relations, theological discourse, and cultural exchanges among these communities.
