For the most part the Shayban remained active, as in pre-Islamic times, mainly in Mesopotamia, but especially in the district of Diyar Bakr, where they settled in numbers, and from there to the adjacent Armenian Highland.

[1] Under the early Abbasid Caliphate, the most prominent Shaybani were the family of Ma'n ibn Za'ida al-Shaybani, a former Umayyad servant who secured the pardon of al-Mansur.

[1] Yazid also served twice as governor of Arminiya, a vast province encompassing current Armenia and Azerbaijan, where carried out large-scale colonization with Arab Muslims, particularly at Shirvan.

He was succeeded by his sons Asad, Muhammad, and Khalid, becoming the first of a long line of Shaybani governors and the progenitor of the Mazyadid dynasty that ruled in Shirvan as autonomous and later independent emirs (Shirvanshah) until 1027.

[1] Some Shayban are mentioned in later times in southern Iraq as poets, grammarians and philologists, chief among them the Shaybani mawla Abu Amr Ishaq ibn Mirar al-Shaybani (died 825).
