The phrase identifies groups of people recognized in Islam as having received earlier scriptures from God prior to the Quran. These groups are generally understood to include Jews, Christians, and sometimes Sabians, who are believed to possess divinely revealed texts, though potentially altered over time. An instance of its use would be in discussions concerning interfaith relations within Islamic societies, legal status, or historical interactions.
Acknowledging this common heritage serves to foster understanding and tolerance. Historically, it provided a framework for the treatment of religious minorities within Islamic rule, granting them a protected status and certain rights. This concept acknowledges shared theological roots and promotes peaceful coexistence despite differing religious practices and beliefs.
