Mulla Husayn, a Muslim cleric in Persia in the 19th century, set out in search of a Messianic figure. In the process he became a significant instrument of God's divine plan, willing to perform all manner of heroic deeds to advance the message of God. This is the saga that recounts his struggle as the first believer in The Bab's message, his recognition of the Bab's station as the Promised Qa'im, his teaching of the other newest followers of the Bab, his pilgrimage and his final martyrdom.
