When Bahá’u’lláh returned from Sulaymáníyyih, He illumined Baghdád with His light: The call of God was raised anew and a tumult arose in Persia. In Baghdád Bahá’u’lláh stood firm before all peoples. The government of Persia was extremely hostile in those days, and all were seeking by every means to cause Him suffering and to bring Him to harm. At last the Persian government, having grown alarmed at His influence, said: “Baghdád is close to Persia and is a place of passage for the Persians. Thus, in order to put out this fire Bahá’u’lláh must be banished to a distant land.” The Persian government then petitioned the Ottoman government, and Bahá’u’lláh was as a result transferred with all due honour out of Baghdád. Leaving the city, Bahá’u’lláh went to the garden of Najíb Páshá and resided there for twelve days. During that time many people, both high and low, and even the Governor and a number of other officials, attained His blessed presence. These are the twelve days of Ridván.

In any event, it was by means of hints and allusions that Bahá’u’lláh first declared His mission during those twelve days. Certain among the friends grasped His intent, but others did not fully understand. At last Bahá’u’lláh came to Constantinople and the Súrih of pilgrimage was revealed, wherein the instruction is given to circumambulate the House of Baghdád. In that Súrih the Cause is openly manifest, but the phrase “He Whom God shall make manifest” does not appear.
