Mullá ‘Alí Bastamí (d. 1846): The second person to recognize the Báb

According to Nabil, twelve of his companions, each independently, also recognized the Báb soon after him and became among the Letters of the Living. The Báb gave Mullá ‘Alí the title "the Second Who Believed" and identified him in His Persian Bayan, in allegorical language, as the return of the Imam Ali – indicative of his high station. Mulla ‘Ali was directed by the Báb to go to the twin cities of Najaf and Karbala in Iraq and announce the Advent of the Promised One. Tahirih (the Pure One), then known as Fátimih Umm-Salamih Baraghání, was in Karbala at that time and therefore heard about the claims of the Báb from Mulla ‘Ali. Mulla ‘Ali was subsequently arrested and tried in Baghdad in January 1845 and later sentenced to work for life in the imperial naval docks, where he died in an Istanbul prison. He is known to be the first Bábí martyr.
