@Aabhas24 Iyas ibn Qabisah al-Ta'i I (from Tayy tribe) was the Sassanid governor of al-Hirah from 602 to 617. The Banu Bakr ibn Wa'il tribe opposed his rule which led to the Battle of Dhi Qar in 609, in which the Sassanids were defeated.

@Aabhas24 Tayy is an ancient Arab tribe. They helped Lakhmids rule Al-Hirah in the 610s. A chieftain & poet of this tribe, Hatim al-Ta'i, is widely known even today through stories (Qissa-e-Hatem-tai ) about his generosity. He lived in Ha'il (Saudi Arabia) & was mentioned in some Hadiths.

@Aabhas24 The Tayy's original homeland was Yemen but in the 2nd century, they migrated to the North Arabian mountain ranges of Jabal Aja and Jabal Salma (traditional homeland of the tribe even today). The two main branches of Tayy were Al al-Ghawth & Al Jadilah.

@Aabhas24 The Fasad War (late 6th century) split the people of Tayy Tribe, with members of its Jadila branch converting to Christianity and migrating to Syria where they became allied with the Ghassanids, and the Ghawth branch remaining in Jabal Tayy (Saudi)
