Islamic Poetry & Mysticism by Reynold Allene Nicholson

Sufism, the religious philosophy of Islam, is described in the oldest extant definition as the apprehension of divine realities, and Muhammadan mystics are fond of calling themselves Ahl al-Haqq, "the followers of the real".The central doctrines from this point of view, have been drawn to some extent on materials collected during the last twenty years from a general history of Islamic mysticism.
