to hard to believe but an esoteric shi'a ismaili sect is the origins of the Mormon theology.
see Kitab al-azilla, Umm al-Kitab and other secret books of the various Ismaili derived sects, also the origins of Masonic beliefs and Joseph Smith was a Mason.
Hence you get Mormon prophets: Jos. Smith, Jos. Morris, George Williams, espousing Ismaili theology of 10 estates or realms of God with an Adam at each level, which is the Isma'ili view on cosmology.
