Shajra e Ismaili, also known as the "Ismaili Genealogy" or "Tree of Ismaili Lineage," is a sacred text that outlines the spiritual lineage of the Ismaili Imams. The term "Shajra" comes from the Arabic word for "tree" or "genealogy," reflecting the document's purpose: to illustrate the connections between the Ismaili Imams and their predecessors. The Shajra e Ismaili is considered a vital part of Ismaili heritage, providing a window into the community's rich history and spiritual traditions.
