BahÃ ' Ã s claim that the BÃ b was also the spiritual return of Elijah and John the Baptist , that he was the `` UshÃ dar-M Ã h '' referred to in the Zoroastrian scriptures , and that he was the forerunner of their own religion . BahÃ ` u 'll Ã h , the founder of the BahÃ ' Ã Faith , was a follower of the BÃ b and claimed to be the fulfillment of his promise that God would send another messenger .
