Traveling through rain and storm, at times even making night marches, the weary travelers, after brief halts at Kú_ch_ík-_Ch_akmá_ch_ih, Buyuk-_Ch_akmá_ch_ih, Salvárí, Birkás, and Bábá-Iskí, arrived at their destination, on the first of Rajab 1280 A.H. (December 12, 1863), and were lodged in the _Kh_án-i-‘Arab, a two-story caravanserai, near the house of ‘Izzat-Áqá. Three days later, Bahá’u’lláh and His family were consigned to a house suitable only for summer habitation, in the Murádíyyih quarter, near the Takyíy-i-Mawlaví, and were moved again, after a week, to another house, in the vicinity of a mosque in that same neighborhood. About six months later they transferred to more commodious quarters, known as the house of Amru’lláh (House of God’s command) situated on the northern side of the mosque of Sulṭán Salím. Thus closes the opening scene of one of the most dramatic episodes in the ministry of Bahá’u’lláh. The curtain now rises on what is admittedly the most turbulent and critical period of the first Bahá’í century—a period that was destined to precede the most glorious phase of that ministry, the proclamation of His Message to the world and its rulers. Chapter X: The Rebellion of Mírzá Yaḥyá and the Proclamation of Bahá’u’lláh’s Mission in Adrianople A twenty-year-old Faith had just begun to recover from a series of successive blows when a crisis of the first magnitude overtook it and shook it to its roots. Neither the tragic martyrdom of the Báb nor the ignominious attempt on the life of the sovereign, nor its bloody aftermath, nor Bahá’u’lláh’s humiliating banishment from His native land, nor even His two-year withdrawal to Kurdistán, devastating though they were in their consequences, could compare in gravity with this first major internal convulsion which seized a newly rearisen community, and which threatened to cause an irreparable breach in the ranks of its members. More odious than the unrelenting hostility which Abú-Jahl, the uncle of Muḥammad, had exhibited, more shameful than the betrayal of Jesus Christ by His disciple, Judas Iscariot, more perfidious than the conduct of the sons of Jacob towards Joseph their brother, more abhorrent than the deed committed by one of the sons of Noah, more infamous than even the criminal act perpetrated by Cain against Abel, the monstrous behavior of Mírzá Yaḥyá, one of the half-brothers of Bahá’u’lláh, the nominee of the Báb, and recognized chief of the Bábí community, brought in its wake a period of travail which left its mark on the fortunes of the Faith for no less than half a century. This supreme crisis Bahá’u’lláh Himself designated as the Ayyám-i-_Sh_idád (Days of Stress), during which “the most grievous veil” was torn asunder, and the “most great separation” was irrevocably effected. It immensely gratified and emboldened its external enemies, both civil and ecclesiastical, played into their hands, and evoked their unconcealed derision.
