The Tayyaye were Christians according to John of the Sedre and the Standard Islamic Narrative. MHMT is the Pahlavi name for Jesus Patibilis, the BeithEl.
The phrase '''Tayyaye of Mahmet''' refers to '''Messianic Mithraists''' of [[Tachkastan]] who had been united to the [[proto-Karaites]] as [[Hagarim]], by Arabian proto-Karaite known by name as [[Mahmet Ismaili]] according to [[Sebeos]]. [[Fredgar]] indicates that they were integrated with the Saracens (Pahlavis) of Ercolia who Khosrow II sent with the Jews to conquer Jerusalem in 610.
