April 21 or 22 (sources differ). On this date in 1863, the Bábis entered the Najibiyyih Garden in Baghdad in preparation for their journey to Istanbul. Because of increasing Bábi harassment of Shi'ite pilgrims, the Qajar government asked for the Bábi leadership based in Baghdad to be extradited to Iran, but the Ottoman government refused and instead chose to move them from the sensitive border. In 1870, during his visit to Iraq, the Najibiyyih Garden served as a guest house for Naser al-Din Shah, who was responsible for Bahá'u'lláh's imprisonment and exile. The location of the gardens today is the Baghdad Medical City, a large complex of teaching hospitals.
