A collection of the long-unavailable tafasir, or commentaries on the Qur'an, which help to properly explain and contextualize the revelation, this series aims to make leading exegetical works—in translation, unabridged, and faithful to the letter and meaning of the Arabic—widely available for study and research. One of the most pivotal works for understanding the environment that influenced the development of Qur'anic exegesis, this volume—originally written by Abdullah Ibn 'Abbas and Ibn Ya'qub al-Firuzabadi—offers valuable insight into the circulation and exchange of popular ideas between Islam, Judaism, and Christianity during the formative phase of Islamic exegesis. In addition, the work avoids elaborate theological, philosophical, and grammatical explanations, making it easily accessible to nonspecialists.
