Book of the Highest Initiation

The Book of the Highest Initiation (also known as “The Book of the Policy and the Highest Initiation” - Arabic: “Kitab as-Siyasa wa’l-Balagh al-Akhbar”) is a text that falsely claims to be of Ismaili origin and is wrongfully attributed to ‘Ubayd Allah, or Abdullah al-Mahdi Billah, the first Fatimid Caliph-Imam. The work is a false account of Ismaili initiation and was written with the intent of denigrating Ismaili beliefs and practices. It is included in the polemic work of the 10th-century anti-Ismaili writer Akhu Muhsin.
