or vicegerency" from his religion. The Báb also decreed no one’s words would be binding upon believers until the advent of the Promised One. Others questioned Yahya’s motives, considering he had never done anything to protect the Bábí Faith or the lives of Bábís over which he was now claiming a high position. To bolster his effort, Yahya simultaneously sought to discredit Bahá’u’lláh by spreading false rumors and accusations about him, which stirred up feelings among Bábís in the Baghdad community. Departure for Kurdistan Declining to dispute with Yahya or do anything to "endanger the unity and survival of the already demoralized Bábí community", Bahá’u’lláh entrusted his family to the care of his brother Mirza Musa and without notice left Baghdad on 10 April 1854 for mountains in the north near Sulaymaniyyih in Kurdistan. He later wrote that he withdrew to avoid becoming a source of disagreement within the Bábí community. Initially living as a hermit in those mountains, Bahá’u’lláh dressed as a dervish and used the name Darvish Muhammad-i-Irani. In Sulaymaniyyih the head of a noted theological seminary happened to meet Bahá’u’lláh and invited him to visit. There a student noticed Bahá’u’lláh’s exquisite penmanship, which raised the curiosity of leading instructors. As he responded to their queries on complex religious themes, Bahá’u’lláh quickly gained admiration for his learning and wisdom. Shaykh ʻUthmán, Shaykh ʻAbdu'r-Rahmán, and Shaykh Ismáʼíl, leaders of the Naqshbandíyyih, Qádiríyyih, and Khálidíyyih Orders respectively, began to seek his advice. It was to the second of these that Bahá’u’lláh’s book the Four Valleys was written. During Bahá’u’lláh’s absence from the Baghdad Bábí community, Mirza Yahya’s true nature became increasingly clear. The public respect and morale of Bábís soon disintegrated as Yahya failed to give spiritual guidance or to demonstrate in daily living the lofty standards taught by the Báb. His actions to discredit Bahá’u’lláh, and any who admired him, grew. At the same time Yahya used the Bábí Faith to benefit himself materially and to try to augment his delusory standing, employing means towards those ends which shamefully contradicted statements by the Báb. He also engaged in criminal activities, including persuading several followers to murder other Bábís whom Yahya viewed as potential adversaries, or as supporters of such imagined rivals. Yahya even took steps to initiate another attempt to assassinate the Shah of Persia. Yahya’s utter failings as a religious leader led most Bábís to reject his claims.
