According to “A Traveller’s Narrative” (p. 16), the Báb “wrote a letter, in the course of the journey, to the Prime Minister, saying: ‘You summoned me from Isfáhán to meet the doctors and for the attainment of a decisive settlement. What has happened now that this excellent intention has been changed for Máh-Kúh and Tabríz?’”
