The Sháh felt his good will and respect for the Shaykh grow
increasingly from day to day. He felt obliged to obey him and would have
considered it an act of blasphemy to oppose him. However, at this time, a
succession of earthquakes occurred in Rayy [a city near Tihran] and many were
destroyed.
The Sháh had a dream in which it was revealed to him that,
if Shaykh Ahmad had not been there, the entire city would have been destroyed
and all the inhabitants killed. He awakened terrified and his faith in the
Shaykh grew apace.” (A. L. M. Nicolas’ “Essai sur le Shaykhisme,” I, p. 21.)
