In Jami's Silsilat al-Dhahab (part of the Haft Awrang), a key theological and Sufi principle is established regarding the definition of true spiritual nobility. Jami argues that physical descent from the Prophet Muhammad (nasab-e tini, or lineage of clay) is spiritually meaningless without a corresponding moral and spiritual alignment (nasab-e dini, or lineage of faith). True affiliation with the Prophet's household (Ahl al-Bayt) is achieved through devout emulation, ethical purity, and spiritual affinity (munasabah), rather than mere biological ancestry. This concept serves to critique those who exploit noble lineages for worldly power and prestige while neglecting inner spiritual cultivation.
