Sin, error and mistake are of the affairs which cause people to be hateful of leaders; so in the Islamic culture, the prophets and Imams (the real leaders) must be infallible. Abbas Effendi and Shoqi Effendi are considered as Imams by the Baha'is.
One of the best and trustful disciples of Abdul Baha is Fadhlullah Sobhi Mohtadi. The Baha'is call him as the writer of inspiration.
However, Sobhi who was admired and praised by Abdul Baha is considered as betrayal by Shoqi Effendi. In the book "Badi'a century, Sobhi is mentioned as "the ex-trustful man of the Excellency Abdul Baha who has disobeyed the next Baha'ism leader.
Now, the question is: Which one of these two Baha'i leaders is true and which one is false? Are Abdul Baha's statements true or false?
