What if either Muhammad was killed before the Hijra or the forces of the Jihad were completely defeated before the Caliphate controls all of the Arabian peninsula? How will this change history?
In many ways, few of them for the better. For one thing the Middle East will in all probability remain divided for some time between two monotheistic empires in a perpetual war until both implode and are replaced by different versions. Given that the ERE was by far the more fragile of the two regimes the Middle East winds up being Persianized and Christianity replaced with Zoroastrianism.
How do you figure Byzantium was more fragile? It survived the Islamic expansion, Persia didn't.
Here's a thought, how would no Islam effect Christianity? Would would Christianity be like without its arch-nemesis? Would Christianity be as dominant in Western Europe without the threat of the Arabs? Maybe paganism would persist longer? At the very least Christianity would fracture more as Coptic Christianity would be stronger, possibly Egypt would split off and Christianity is divided between the Catholic, Orthodox and Coptic world.
I'm unsure of Zoroastrianism displacing Christianity, fan though I am of the former. Zoroastrianism didn't have much of a proselytizing tradition, and the version practiced by the aristocrats differed from the Mazdism of rural Iranians and the Steppe.
I could see Zoroastrianism becoming the popular religion of the burgeoning merchant classes and urban elites of NE if the Persians are able to sustain dominance of the area for a few generations.
I agree with your sentiments on how miserable European Jewry is going to be ITTL. Persia would probably treat them well; I don't recall the Sassanids being particularly anti-Semitic. Perhaps "Next year in Jerusalem" becomes a bit more imperative and we see Jews leave Europe for the ME and North Africa.
Or maybe they move North and we get some Jewish Vikings
Because of how many times the Persians captured Byzantine Emperors and the not-so-minor reality that Khosroes II had shown that the ERE was vulnerable to any sufficiently willing and capable Sassanian who attempted to finish the job. I might note that instead of Muslims ruling Jerusalem and the Coptic Patriarchate, it will be Zoroastrians, as around the time that the ERE starts persecuting the Monophysites and a foreign army comes knocking......
Christianity without Islam will fixate on Jews a lot more than it did IOTL with horrific consequences for the Jews, who will have no Caliphates to foster the growth of independent Jewish scholarships and no places of refuge whatsoever from the Church's established patterns of repression and thuggery aimed at them. Or alternately it just replaces its fear of the Muslim Other with a Zoroastrian Other and invents Medieval myths of Moloch and passing children through the fire to ensure that the Church knows the infidels are bad people. Medieval Christianity was a brutal, intolerant, xenophobic religion of thugs so it's not like it would be very difficult or cost the Church too much sleep at night to invent blatant lies about an actually non-Abrahamic religion given how they twisted and warped Islam IOTL.
Given that the Sassanian nobility was tied to Zoroastrianism, and given that it's likely to conquer Egypt and Palestine in any renewed, post-plague, no-Islam war with the ERE and hold them, I can see it but from an opportunistic "let's make more money" POV like most of the early conversions to Islam. Zoroastrianism would replace Islam as Christianity's Bogeyman and the same types of smears, lies, and outright distortions applied to Islam would apply to Zoroastrianism. Probably the Church would invent practices of passing eldest children through the fire and associate Ormazd with Moloch instead of claiming Muslims were schismatic-heretic Christians.
Eh, the Sassanians had bouts of persecution and were rather more zealously Zoroastrian than other Persian dynasties were. I doubt they'd match the ERE or Christian states in that regard but that's not a ringing endorsement.
No, they will not stay Arian, because they were already Catholics. The Visigoths adopted Catholicism and the Roman-Iberian culture during the rule of King Rekhared I between 586 and 601.I'm not sure about Persia stability following Heraclius' campaigns, though it is conceivable that if they had time to recover they could have taken Egypt and Syria. I think by that point it was just a matter of time before the Byzantines lost that for good. But at this point the Byzantines still control North Africa, Italy and parts of Spain. The Visigoth Kingdom would also survive for the forseeable future, and may stay Arian.

That would be extremely interesting with Zoroastrianism taking the place of Islam in the West as the enemy. I guess Hinduism would probably stay more prominent in South Asia and maybe the Tang Empire would last a bit longer in China. This would make for a very interesting timeline.

The Persians greatest enemies were in the east, not the west, and Constantinople is much more defensible than Ctesiphon, by location alone.
The Persians will never take the Romans capital, the Romans sacked the Persian's capital on many occasions. They couldn't conquer each other, but I'd say that the ERE is more likely to survive a war with Persia.
