According to Mírzá Abu’l-Fadl, Hájí Mírzá Aqásí sought, by his reference to the rebellion of Muhammad Hasan Khán, the Salar, in Khurásán, and the revolt of Áqá Khán-i-Isma’ílí, in Kirmán, to induce the sovereign to abandon the project of summoning the Báb to the capital, and to send Him instead to the remote province of Ádhirbayján.
Fearing that the presence of the Báb in Tihrán would occasion new disturbances (there were plenty of them due to his whims and his poor administration), he altered his plans and the escort, charged to take the Báb from Isfáhán to Tihrán, received, when about thirty kilometers from the city, the order to take the prisoner directly to Máh-Kú. This town, in the mind of the prime minister, would offer nothing to the impostor because its inhabitants, out of gratitude for the favors and protection they had received from him, would take steps to suppress any disturbances which might break out.” (Journal Asiatique, 1866, tome 7, p. 356.)
