A translation of the Book of Worship by the eleventh-century writer Al-Ghazzali, this is a useful book which explains elements of Muslim worship for those who desire to know more. The Introduction brings together the acts and utterances which constitute the formal ceremony called “the Worship” which is still practiced today, and gives an account of the times when this ceremony is used in the religious life of the Muslim. Annotations help clarify allusions and technical terms, the knowledge of which al-Ghazzali takes for granted as he wrote his description of the Worship for Muslims.
