Mírzá Yahyá, known as subh-i-Azal (Morning of Eternity), [was] a younger half-brother of Bahá’u’lláh, [by thirteen years] …arose against Him and opposed His Cause. Mírzá Yahyá was nominated by the Báb to serve as a figurehead for the Bábí community pending the imminent manifestation of the Promised One. At the instigation of Siyyid Muhammad-i-Isfahání, Mírzá Yahyá betrayed the trust of the Báb, claimed to be His successor, and intrigued against Bahá’u’lláh, even attempting to have Him murdered. When Bahá’u’lláh formally declared His Mission to him in Adrianople, Mírzá Yahyá responded by going to the length of putting forward his own claim to be the recipient of an independent Revelation. His pretensions were eventually rejected by all but a few, who became known as Azalís. He is described by Shoghi Effendi as the “Arch-Breaker of the Covenant of the Báb”
