Bahá'u'lláh sends Nabíl-i-A`zam to Cairo to enquire after Hájí Mírzá Haydar-`Alí. He is thrown into prison and befriends a Christian cellmate, Fáris Effendi, who soon becomes a Bahá'í. [BKG248, 265–6; EB268; GPB178]
See BKG265–8 for an account of Nabíl's arrest and imprisonment.
Fáris Effendi is probably the first Christian to become a Bahá'í. [RB3:10]
Two believers were arrested during the same period. Hájí Amín was sent to the prison of Qazvín, and Hand of the Cause Ibn-i-Abhar was consigned for four years in Tíhran, in which he bore the same chains as Bahá'u'lláh did, during the Latter's imprisonment in 1852.[Essay by Mehdi Wolf]
