Explanation to the Belief of Mahdism in Shi'a Imamia

  1. The 4th ambassador and the end of the period of his embassy ===============================================================

The long absence (Ghaybat Kubra) was an anticipated one during the short one (Ghaybat Sughra). In that period books too were written about this subject. No ambassador was appointed after Ali Bin Mohammed Saruri. The reason is not known. It could be that the Imam did not find a trustworthy one. It could be this that the Nawabs of the period of short Ghaybat were to acquaint the people with the coming Ghaybat that was going to be indefinitely long.
