I found some stuff that appears to condone suicide among Baha'is, or at least shows that prominent adherents of the faith in the early days committed suicide because of a desire to be joined with God.
Baha, in the Lawh-i-Raiz, alluded to this event, saying, "One from amongst the Friends sacrificed himself for myself and cut his throat with his own hand for the love of God. This is such that we have not heard from former ages. This is that which God hath set apart for this dispensation." Another disciple attempted suicide about the same time. [2] This "old and faithful follower seized a knife and exclaiming, 'If I must be separated from my Lord, I will go and join my God, cut his throat. With the aid of a physician, his life was saved. Again when the ship bearing the exiles reached Haifa, Abdul Ghaffar, finding himself to be separated from his Lord, determined to sacrifice his life, and threw himself into the sea from the steamer, exclaiming, 'O Baha! O Baha!'" The sailors rescued him. [3] This tendency to suicide reveals an astonishing degree of fanaticism among the Bahais.Bahaism and Its Claims, p. 239 (author not provided)
