There are small traces of Iranian Ismaili communities in the post Alamut era. Sporadic prose or odes in fear and anxiety, here and there, dug in the ground or in a wall crack have been extant. Most are prayers and supplications which throw a little light on the dark centuries; however the poem of Mahmoud is totally different. The intoxicated poet, free from fear, unfolds the secrets. For a small religious group, taken refuge in a remote mountainous castle or dwelled around a horrific desert what would be the most crucial secret? The name of the leader? The name of their settlements and shelters? the name of their local leaders and hierarchies? All are revealed in the poetry of Mahmud. Critically edited the single manuscript and based on the historical method, this paper contributes to analyze and to reveal some facts such as: geographical domain of Qasim shahi, the names of local leaders and hierarchies in call (Da’wa) and contemporary beliefs in 11th / 17th century.
