The Kitab Al-Luma Fi L-Tasawwuf: Of Abu Nasr Abdallah B. Ali Al-Sarraj Al-Tusi

The Kitab al-Lumaʿ fi al-Tasawwuf by Abu Nasr al-Sarraj al-Tusi, translated and edited by Reynold A. Nicholson, is one of the earliest comprehensive manuals on Sufism. Written in the 10th century, it outlines the doctrines, practices, terminology, and spiritual states of the Sufi path. Al-Sarraj defends Sufism against critics and provides biographies of early mystics, offering deep insight into their inner experiences and teachings. Nicholson’s scholarly translation preserves the depth and authenticity of the original text, making it a foundational source for understanding classical Islamic mysticism and the historical development of Sufi thought and practice.
