The phrase '''Tajh of Mehmet''' refers to the '''Arabian Messianic Mithraists''' of [[Tachkastan]] who had been united to the [[proto-Karaites]] as [[Hagarim]] by [[Mehmet Ismaili]], the first known '''Tajh of Mehmet''' as named by [[Sebeos]].
[[Mehmet Ismaili]] could have been the historical 7th century figure behind the Islamic legends of [[Al-Iyas ibn Qabisa]] and [[Muhammad ibn Abdullah]]. But he is not the [[Mehmet]] for whom the '''Tajh of Mehmet''' are named.
