What outlast? there a reason why Caliph Utman(PUH) didn't wanted to fight them, too insane at the time and once both have a border on tigris they just focus on peace as the Persian cared more about India and Central asian than meditteranean.and is a powerful state, and it's even managed to outlast Islamic power in the Middle East;
depends when he is killed if dies of in nineveh nothing much since Constantine III is old enough to be emperor the same goes if he dies in 626 (the siege was won with out him) and heck even 625 would need to die very early on a good place would be antioch in 613 or have the avars kill him in 622.I would say that the Sassanids need to avoid the reing of Hormizd IV and return to the pre Khosrau I status quo. If this is done, the Sassanid royalty can repair relations with the noble houses and also have a more efficient governmental spending policy. The Sassanid elites will not have to expend revenue (which depended upon successful war loot) on wasteful and poorly performing standing armies. All funds can go to constructing free cities to acquire greater state revenues and then in outfitting the Great Houses with gifts to sponsor more disciplined and strong cavalry-based armies. This will maintain the same sort of keen military prowess that the Arsacids and early Sassanids were famous for and hence avoid the disasters of the Arab victories across Mesopotamia. In the slightest, after initial defeats, they will recover, having still a coalition of the Great Houses and hence overwhelm the Arabs with cavalry.
In Byzantium, I am not sure. Time the Arab invasion during a civil war similar to the one following the death of Emperor Maurice. Say, instead of Heraclius asserting his power, he is slain too.. If the post changes more than three times in a single war, the Arabs may be able to take Constantinople through a combination of deception, treason and brute force. Meanwhile, the Sassandis either hold everything east of the Euphrates or east of the Zagros.

so a pod of he dies in 628 after war is well stable he already won and there are no other claimants since Heraklonas is not old enougth to be emperor and the sassanids are killing eachother so it defeats the whole point of the pod , but if you have heraclius die in 613 thats at least in some time is a persian wank same for 622 but to a lesser extend but then if the war ends circa 615 you can still have khosrow II cause another civil war despite his victory.
OCC: I know forgot the put the OCC when talking to Jonh thoOOC: This a DBAHC from a timeline where the Byzantines fell and the Sassanids survived.
