It may be this to which allusion is made in a tradition preserved by Behîah Khanum, sister of Abbas Effendi Abdul Baha, that Ṣubḥ-i-Ezel claimed to be equal to his half-brother, and that he rested this claim on a vision. The implication is that Baha-'ullah was virtually the head of the Bābī community, and that Ṣubḥ-i-Ezel was wrapt up in dreams, and was really only a figurehead. In fact, from whatever point of view we compare the brothers (half-brothers), we are struck by the all-round competence of the elder and the incompetence of the younger. As leader, as teacher, and as writer he was alike unsurpassed. It may be mentioned in passing that, not only the _Hidden Words_ and the _Seven Valleys_, but the fine though unconvincing apologetic arguments of the _Book of Ighan_ flowed from Baha-'ullah's pen at the Baghdad period. But we must now make good a great omission. Let us turn back to our hero's origin and childhood. Ḥuseyn 'Ali was half-brother of Yaḥya, i.e. they had the same father but different mothers. The former was the elder, being born in A.D. 1817, whereas the latter only entered on his melancholy life in A.D. 1830. [Footnote: It is a singular fact that an Ezelite source claims the name Baha-'ullah for Mirza Yaḥya. But one can hardly venture to credit this. See _TN_, p. 373 n. 1.] Both embraced the Bābī faith, and were called respectively Baha-'ullah (Splendour of God) and Ṣubḥ-i-Ezel (Dawn of Eternity). Their father was known as Buzurg (or, Abbas), of the district of Nūr in Mazandaran. The family was distinguished; Mirza Buzurg held a high post under government. Like many men of his class, Mirza Ḥuseyn 'Ali had a turn for mysticism, but combined this--like so many other mystics--with much practical ability. He became a Bābī early in life, and did much to lay the foundations of the faith both in his native place and in the capital. His speech was like a 'rushing torrent,' and his clearness in exposition brought the most learned divines to his feet. Like his half-brother, he attended the important Council of Badasht, where, with God's Heroine--Ḳurratu'l 'Ayn--he defended the cause of progress and averted a fiasco. The Bāb--'an ambassador in bonds'--he never met, but he corresponded with him, using (as it appears) the name of his half-brother as a protecting pseudonym. [Footnote: _TN_, p. 373 n. 1.]
