Shoghi Effendi elaborates Baha’u’llah’s station in God Passes By:
"To Israel He was neither more nor less than the incarnation of the “Everlasting Father,” the “Lord of Hosts” come down “with ten thousands of saints”; to Christendom Christ returned “in the glory of the Father,” to Shi’ah Islam the return of the Imam Husayn; to Sunni Islam the descent of the “Spirit of God” (Jesus Christ); to the Zoroastrians the promised Shah-Bahram; to the Hindus the reincarnation of Krishna; to the Buddhists the fifth Buddha."
From here.
