Mullá Husayn, as soon as he had won to the Cause such able and devoted supporters, decided to address a written report concerning his activities to the Báb. In his communication he referred at length to his sojourn in Isfáhán and Káshán, described the account of his experience with Bahá’u’lláh, referred to the departure of the latter for Mázindarán, related the events of Núr, and informed Him of the success which had attended his own efforts in Khurásán. In it he enclosed a list of the names of those who had responded to his call, and of whose steadfastness and sincerity he was assured. He sent his letter by way of Yazd, through the trustworthy partners of the Báb’s maternal uncle who were at that time residing in Tabas. That letter reached the Báb on the night preceding the twenty-seventh day of Ramadán,  a night held in great reverence by all the sects of Islám and regarded by many as rivalling in sacredness the Laylatu’l-Qadr  itself, the night which, in the words of the Qur’án, “excelleth a thousand months.” The only companion of the Báb, when that letter reached Him that night, was Quddús, with whom He shared a number of its passages.
I have heard Mírzá Ahmad relate the following: “The Báb’s maternal uncle himself described to me the circumstances attending the receipt of Mullá Husayn’s letter by the Báb: ‘That night I saw such evidences of joy and gladness on the faces of the Báb and of Quddús as I am unable to describe. I often heard the Báb, in those days, exultingly repeat the words, “How marvellous, how exceedingly marvellous, is that which has occurred between the months of Jamádi and Rajab!” As He was reading the communication addressed to Him by Mullá Husayn, He turned to Quddús and, showing him certain passages of that letter, explained the reason for His joyous expressions of surprise. I, for my part, remained completely unaware of the nature of that explanation.’”
