It seems first that the Ghassanid Monophysite Church entered a brief union with Heraclius at this time.
Skirmishes between Tachkastan's Arabs and the Zoroastrian-ruled Ghassanids seem to have taken place with the battle of [https://en.wikipedia.org/wiki/Mu%27tah Mu'tah, Jordan], in September 629 and again at Al Karak in 630 as Heraclius made his way to recapture the Holy Land. Heraclius interviews Abu Sufyan of Quraysh concerning the Banu Qabisa of Tachkastan. Quraysh decide to submit to the Banu Qabisa of Tachkastan and the Standard Islamic Narrative indicates that Heraclius orders the Ghassanids to submit to the Noahite Manicheans as well. This could be why '''the Syriac Orthodox decided to break ties with Heraclius'''.
