Interrogating the ideological framework of late antiquity, Salama exposes hidden assumptions that prevent scholars from truly placing Islam in its sociohistorical and cultural milieu. He offers an alternative theoretical and practical model focused on pre-Islamic Arabic cultural production. Foregrounding the indigenous Arab community of seventh-century Hijaz, Salama demonstrates how the Qurʼān played an organic role in commenting on, interacting with, and taking sides concerning matters of ethnicity, ethics, dress codes, and social habits. Only with renewed attention to the Qurʼān itself can Western readers engage ethically with Islamic studies and with the cultures and traditions of those who live according to another book.
