Bahā’u’llāh, The Kitābi Aqdas, paragraph 32
“The Lord hath ordained that those of you who are able shall make pilgrimage to the sacred House, and from this He hath exempted women as a mercy on His part.”
The Baha’is make the pilgrimage to the International Baha’i Center, which is located in the Palestinian cities of Acre and Haifa (currently under Israeli occupation).
The first includes the tomb of Baha’u’llah, while the second includes the shrine of Ali Muhammad al-Shirazi, known as the Bab. The site of this ritual is located in Baghdad and Shiraz respectively.
