Shahr-Bánú Khánum (Persian: شهربانوخانم ) was the daughter of Mírzá Muḥammad-Ḥasan, Bahá’u’lláh's older half brother.
In the 1850's Shahr-Bánú's father visited Baghdad and arranged for her to marry ‘Abdu’l-Bahá,[1] however her father passed before they were of marrying age and she fell under the care of her uncle Hají Mírzá Riḍa-Quli. When Bahá’u’lláh sent a representative to negotiate with Riḍa-Quli to make arrangements for the marriage he cancelled the proposal fearing the impact it would have on his relationship with the nobility of Iran.[2]
Shahr-Bánú's aunt Shah-Sultan Khanum arranged for her to marry Mírzá ‘Alí Khan who was the son of the Grand Vizier of Iran Mírzá Aqa Khan.[3] She was unhappy in the marriage, contracted consumption, and passed away at a young age.[2]
