March 1845: The Báb sent an epistle to His followers in Karbila directing them to proceed to Isfahan – this “created a considerable stir among those who had been eagerly awaiting” His arrival at Karbilá

Soon after Naw-Rúz, an epistle reached them by way of Basrih, in which the Báb, who had intended to return from Hijáz to Persia by way of Karbilá, informed them of the change in His plan and of His consequent inability to fulfil His promise. He directed them to proceed to Isfáhán and remain there until the receipt of further instructions. “Should it be deemed advisable,” He added, “We shall request you to proceed to Shíráz; if not, tarry in Isfáhán until such time as God may make known to you His will and guidance.”

The receipt of this unexpected intelligence created a considerable stir among those who had been eagerly awaiting the arrival of the Báb at Karbilá. It agitated their minds and tested their loyalty. “What of His promise to us?” whispered a few of the discontented among them. “Does He regard the breaking of His pledge as the interposition of the will of God?” The others, unlike those waverers, became more steadfast in their faith and clung with added determination to the Cause. Faithful to their Master, they joyously responded to His invitation, ignoring entirely the criticisms and protestations of those who had faltered in their faith. They set out for Isfáhán, determined to abide by whatsoever might be the will and desire of their Beloved. They were joined by a few of their companions, who, though gravely shaken in their belief, concealed their feelings. Mírzá Muhammad-‘Alíy-i-Nahrí, whose daughter was subsequently joined in wedlock with the Most Great Branch, and Mírzá Hádí, the brother of Mírzá Muhammad-‘Alí, both residents of Isfáhán, were among those companions whose vision of the glory and sublimity of the Faith the expressed misgivings of the evil whisperers had failed to obscure. Among them, too, was a certain Muhammad-i-Haná-Sab, also a resident of Iṣfáhán, who is now serving in the home of Bahá’u’lláh. A number of these staunch companions of the Báb participated in the great struggle of Shaykh Tabarsí and miraculously escaped the tragic fate of their fallen brethren.

The Báb was sought after everywhere in Shriraz

“These ethics taught by a young man at an age when passions were intense, deeply impressed an audience, religious to the point of fanaticism, above all when the words of the preacher were in perfect harmony with his conduct. No one doubted the continence and the firmness of Karbilá’í Siyyid ‘Alí-Muhammad; he spoke little, meditated constantly and most of the time fled from the presence of men, which all the more aroused their curiosity. He was sought after everywhere.”

…..

“By the uprightness of his life the young Siyyid served as an example to those about him. He was willingly listened to when, in his ambiguous and interrupted talks, he condemned the abuses evident in all classes of society. His words were repeated and elaborated upon and they spoke of him as the true Master and gave themselves to him unreservedly.”

The early impact of the Báb on Shiraz – by French diplomat Comte de Gobineau (1784–1858)

“Be that as it may, the resultant impression was immense in Shíráz and all the learned and religious gathered around ‘Alí-Muhammad. As soon as he appeared in the Mosque, they surrounded him and, as soon as he was seated in the pulpit, everyone was silent in order to listen to him. His public talks never attacked the essentials of the Faith of Islám, they respected most of its ritual; in fact, the Kitman dominated. Nevertheless, they were daring discourses. The clergy was not spared; its vices were cruelly lashed. The sad and painful destiny of humanity was generally the theme. Here and there, certain allusions, the obscurity of which irritated the passions of some while it flattered the pride of others already initiated as a whole or only in part, gave to his prophecies such a bitter truth that the crowd was growing day by day and so, in all Persia, they were beginning to talk of ‘Alí-Muhammad.

“The Mullás of Shíráz had not waited for all this agitation to unite against this young detractor. From his first public appearances, they sent to him their most able Mullás to argue with him and confuse him, and these public debates were held either in the Mosques or in the colleges in the presence of the Governor, the military chiefs, the clergy, the people, in fact before everyone. But, instead of benefiting the clergy, they contributed quite a little to spread and exalt, at their own expense, the renown of this enthusiastic teacher. It is a fact that he defeated his adversaries, he condemned them—which was not very difficult—with the Qur’án in hand. It was an easy matter for him to show before all these crowds who knew the Mullás well, at which point their conduct, their precepts, and to what extent their beliefs, even their theology, were in flagrant contradiction with the Book, which they could not deny.
