Who is `Abbas Effendi, `Abdu’l-Bahá?
He is from the first wife of Mirzá Husayn-Ali Núri, Nawwabah. Baha’u’llah had three other children from his other wife, Mahd-e Olia, and his other son Muhammad `Ali Effendi was among them. According to the Will and Testament of Baha’u’llah, after `Abdu’l-Bahá, Muhammad `Ali should succeed him, but after the death of Baha’u’llah, numerous disputes occurred between the brothers. `Abbas Effendi called the followers of his brother the ‘covenant breakers’ and named themselves the covenants.
All of this happened while `Abdu’l-Bahá himself has said: …fair notice should be given to a person that is crippled for nurturing his own children and family; How could we put faith in such a person’s guidance for all humans, is there any doubt and uncertainty for this matter? Indeed there is not!
