After the eventual discovery of Tar Village, this fire temple was renamed Baba-Abdullah in fear for it being destroyed under the guise was existing as a non-Islamic institution of worship. The original name of this fire temple is unknown. Upon the arrival of the Arab conquest there was also a change of its role, possibly into a mosque, before it was abandoned.
