Omar offers a fresh and insightful narrative of a timeless, ubiquitous, protean, and always engaging figure in Islamicate literature and lore. He draws on a wide range of sources, from exegesis of the Qur’an’s Sura of the Cave (18) to mystical texts elaborating on Al-Khi?r’s unique spiritual credentials. Omar emphasizes throughout Al-Khi?r’s role as an interreligious cross-cultural symbol of mediation and liberation from stereotypes—an ‘initiator’ who continually surprises with manifestations of his stature and versatility as a paradigmatic sage and mentor.
