The Tayyaye or Taji (tʾcyk') were a North Arabian Tribe associated with Adoptionism from the Formerly Roman Province of Tachkastan which was conquered by the Persians in 610AD.
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 founder of the Abbasid dynasty was Muhammad Al-Imam who took control in 716. He tried to unite the Mawali and the Sunnis.
Under Abbasid influence a new Quran using materials from the Umayyads "book of the Arabs" and from the Mawali's [[Ahsana al-Hadith ]] was composed.
Ultimately the Abbasid attempt at egalitarianism backfired. No doubt the Arabs would never have come on board if they felt they did not own the revelation. So the Abbasids granted them that but in the end their attempt to unite the Arabs and Mawali inevitably kept the religious views of Mawali suppressed in exchange for higher social status. Hence the Sufi circles have never really had any regard for Islam.
