Mullá Husayn, who, while in that city [Kangavar], led the companions of the Báb in the Friday congregational prayer, was held in such esteem and reverence by his fellow-disciples that a number of those present, who later on, in Shíráz, revealed their disloyalty to the Faith, were moved with envy. Among them were Mullá Javád-i-Baraghání and Mullá ‘Abdu’l-‘Alíy-i-Haratí, both of whom feigned submission to the Revelation of the Báb in the hope of satisfying their ambition for leadership. They both strove secretly to undermine the enviable position achieved by Mullá Husayn. Through their hints and insinuations, they persistently endeavoured to challenge his authority and disgrace his name.
