query: What is the significance of the Risāla al-mūjaza in the Isma'ili movement?
answer: The Risāla al-mūjaza is the only known Isma'ili treatise on the qualifications and duties of an Isma'ili missionary (dāʿī). It combines theological instruction with practical advice, emphasizing strict obedience to the Caliph-Imam and considers all other authorities illegitimate.  Its strategy aimed to win recruits before the conversion or overthrow of local rulers.
