This is the first full-length monograph to explore Sufism in Saudi Arabia since 1979-a groundbreaking journey into a rarely seen side of the kingdom's religious life. Drawing on rich fieldwork, in-depth interviews with Sufi practitioners, and archival research, the book brings readers deep into the spiritual networks that persist beneath the surface of state-enforced Wahhabi orthodoxy. It traces a century of scholarly life in the Hejaz, follows transnational ties-especially those of the Ba ?Alawi order-and uncovers stories of persecution, such as that of Muhammad Alawi al-Maliki. Timely and vivid, it also examines the profound religious shifts unfolding under the rule of Mohammed bin Salman.
