This 1935 English translation of a classic Arabic text in Sufism, the mystical aspect of Islam, by A. J. Arberry preserves the beauty and simplicity of the original without departing from a literal translation. Little is known of the author of this treatise Abu Bakr al-Kalabadhi, except that he was a lawyer and died in Bukhara in about AD 990. This book is the work on which his fame rests, and is important because it is the earliest extant text to reconcile the position of Sufism and orthodox Islam. The book consists of five parts: a general introduction to the term Sufi and an enumeration of the names of the great Sufis; a statements of the tenets of Islam, as accepted by the Sufis; a discussion of the various 'stations' of the Sufis; and a discussion of the various phenomena of Sufism. This is a superb English introduction to Sufism.
