According to "A Traveller's Narrative" (p. 16), the Bab remained forty days in Tabriz. According to Haji Mu'inu's-Saltanih's manuscript (p. 138), the Bab spent the first night, on His arrival in Tabriz, in the home of Muhammad Big. From there He was transferred to a room in the Citadel (the Ark) which adjoined the Masjid-i-'Ali Shah.
