Sassanid's win the Battle of al-Qādisiyyah

The Battle of al-Qādisiyyah was one of the most decisive battles between the expanding Muslim Arabs and the declining Sassanid Empire.

After the battle the Sassanid rule in what is modern day Iraq was pretty much doomed.

So what do you all think the long and short term results of a major Sassanid victory be? At the very least if the Empire holds out against the Arabs then Zoroastrianism could still be a major religion even today.

Depend on what kind of victory Sassanid get


if Arab managed to retreat to desert, then Sassanian just get small breathing time.


if Sassanid managed to kill Abu Ubaidah ibn al-Jarrah, and Khalid ibn Walid, and destroy Muslim Army Syrian contingent. Islam itself could suffer from great setback and disappear.
 
It seems unlikely that the Sasanians would have a full revival by this time. Mesopotamia, the beating heart of the Empire in pretty much every way, was lost and the Arabs we doing quite well in the West too.

If the Sassanid Empire manages to win the Battle of Qadissiyah in 637 CE (and especially if it won against the Byzantine Empire some 10 years earlier, leaving them in a much stronger position by 637 than OTL), then the Sassanids could perhaps move their capital to Hamadan (their summer capital) or somewhere else in the Iranian highlands. That could prolong the Sassanid dynasty enough to thwart the massive spread of Islam in Iran and Central Asia (though maybe there'd be individual converts to Islam, and an Arab Muslim concentration around Ahvaz in today's SW Iran), and Zoroastrianism could remain the main religion for 1-2 more centuries. After that, most people there (plus the Turks) would probably have converted to Nestorian Christianity, especially given that it was already increasingly appealing to many Sassanid subjects (especially but by no means exclusively in Mesopotamia). Zoroastrianism would be eventually reduced to a 5-10% minority in our days (cf. Copts in Muslim Egypt) - much larger than in today's OTL Iran. In Central Asia, the people would have maybe kept more of their religious melting pot of Christianity, Zoroastrianism, Buddhism, etc.

Well I main major as in they rout the Arab army.

That could force the Muslims to draw more forcers from the west to fight the Sassanid's. OTL the Arabs were insanely lucky to do as well as they did.

A prolonged war against both the Byzantines & Sassanids is not good for them, not even slightly particularly if those two cooperate against the interlopers.
