Originally published in 1950. Thinkers such as Ghazali and Ibn `Arabi, poets such as Ibn al-Farid, Rumi, Hafiz and Jami were greatly inspired by the lives and sayings of the early Sufis. This book was the first short history of Sufism to be published in any language, illustrating the development of its doctrines with numerous quotations from literature.

Originally published in 1969. This volume was composed by an eminent Sufi mystic whilst in prison in Baghdad, awaiting execution, in a vain attempt to overthrow his sentence; he was put to death in AD 1311 at the age of 33. This apologia is a document of great poignancy, composed in most elegant Arabic and translated with the customary skill and elegance for which A J Arberry became so well-known.
