The phrase '''Tayyaye of Mehmet''' refers to '''Messianic Mithraists''' of [[Tachkastan]] who had been united to the [[proto-Karaites]] as [[Hagarim]], by Arabian proto-Karaite known by name as [[Mehmet 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. From 632 until 680 the "Mahmet People" were commanded by the proto-Karaite Alids. We hear of the '''Tayyaye of Mehmet''' Hagarim is from Thomas the Presbyter when they were fighting (in alliance with the proto-Karaite Bakr family 's khalid) against the Romans in 634 just 12 miles east of Gaza. In 636, the proto-Karaite Emir of the Bakr family 's Emir accepted the surrender of the Yazdegard's Sassanians who assisted him in conquering Syria where they rose in prominence as the Quraysh Hagarim. Meanwhile the proto-Karaite Alids' Ercolian -Pahlavi '''Tayyaye of Mehmet''' Hagarim rose in the East to establish their Imamate in Persia. The standard Islamic Narrative places the origin of the Quran under the Bakr's Quraysh Hagarite Uthman while the two factions were still united. Then in 656 a civil war broke out between the Bakrs' Quraysh Hagarim and the Alids' Pahlavi Hagarim. The proto-Karaite Bakr family were conquered by the '''Tayyaye of Mehmet''' Hagarim while the Bakrs' Quraysh Hagarim withdrew to fortify themselves in Syria. In 680 the Quraysh Hagarim of Syria assasinated the Alids of the New Persian Empire giving the proto-Karaite Bakr Family an opportunity to take back control of the Empire again promoting Uthman's Quran until Abdul Malik succeeded in imposing the rule of the Quraysh Hagarim in 692 AD. Abdul Malik decided that it was in his best interest to revise the religion to abolish the importance of the proto-Karaites. A new Qibla in the Hejaz was established. The Quran was revised. Under the rule of the Quraysh, the Persian cavalries were abolished and Messianic Mithraism evolved into Islam as we know it.
[[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 '''Tayyaye of Mehmet''' are named.
