Sunni Muhammadens have to become Shiah to become Bahá'í

Ali was the true head of the Moslem Faith and the First Imam, not the Caliphs. The Caliphs put Ali fourth but He was the first Imam. Shiah Islam is the closest to the truth not Sunni. The Sunni Muhammadens have to become Shiah to become Bahá'í.
