He [Bahá’u’lláh] derived His descent, on the one hand, from Abraham (the Father of the Faithful) through his wife Katurah, and on the other from Zoroaster, as well as from Yazdigird, the last king of the Sásáníyán dynasty. He was moreover a descendant of Jesse, and belonged, through His father, Mírzá ‘Abbás, better known as Mírzá Buzurg—a nobleman closely associated with the ministerial circles of the Court of Fatḥ-‘Alí Sháh—to one of the most ancient and renowned families of Mázindarán.
