The Book of the Sage and Disciple (Arabic: كتاب العالم والغلام ; Kitāb al-‘ālim wa-l-ghulām) is a religious narrative of spiritual initiation written in the form of a dramatic dialogue by Ja‘far bin Manṣūr al-Yaman (270 AH/883 CE – c. 347 AH/958 CE). The work describes the encounter of a disillusioned young man with a dā‘ī, or Ismāʿīlī Muslim missionary, who gradually introduces his new disciple to the inner dimensions of Islam as elaborated by the Shī‘ī imāms.
