 Since the Islamic Revolution of 1979 Iranian Bahá 'ís have regularly had their homes ransacked or have been banned from attending university or from holding government jobs , and several hundred have received prison sentences for their religious beliefs , most recently for participating in study circles . Bahá 'í cemeteries have been desecrated and property has been seized and occasionally demolished , including the House of Mírzá Buzurg , Bahá 'u'lláh 's father . The House of the Báb in Shiraz , one of three sites to which Bahá 'ís perform pilgrimage , has been destroyed twice .
