The Roman-Persian war ended in 629, the Quran didn't exist until after 632. But even assuming that Mohammed did predict who would before the fighting ended, so what? If he guessed the outcome randomly he'd still have a 50% chance of being right.
Predicting that a staunch enemy of a religion will die without converting to that religion has a very high (although not certain) chance of being true. Not impressive in the slightest.
A thought occurs to me. The Quran wasn't written until after Mohammud died, so how can we be in any way sure that the "predictions" that are supposed to have come true were not added retrospectively to bolster the reputation of their prophet?
How do we know it was correct? Looking it up, the only source I can find that supports this claim is the Quran itself. If there's nothing to support this claim other than the fact that it's mentioned in the Quran, then why should we take it as evidence of the Quran's accuracy?
The Quran borrowed heavily from the Bible. This prediction is clearly taken from Deuteronomy 30:1-5.
So you admit that the Quran was wrong? The Pharoah died long, long ago, so it's clearly wrong..
Or are you talking about the Egyptian practice of embalming and preserving the bodies of the Pharaohs? All Pharaohs got that treatment and this was well known practice even in Mohammad's time. It was done by humans, not God, and everybody knew about it. No special revelations here.
Rediscoverd at what time? Looking up that city, all I find is that in 1996 an amateur archaeologist claimed to have found the remains of that city at Shisr in Dhofar province, but later realized that he was wrong. A later report in 2002 by a geology professor revealed that the NASA satellite data that the claim had been based on was misleading, and the site was just an isolated watering hole with a single building.
There's no evidence that this city the Quran claims that God destroyed ever existed.
If it was God protecting the Quran from changes/corruption, why did Uthman ibn Affan find it necessary to compile a standardized Quran in 653 and send copies of it to every province along with orders that all other Qurans were to be burned?
People who are convinced that the text is true also happen to believe that it's reliable? So what?
Catholicism is just one of the many denominations of Christianity, so that leaves Islam still sitting at #2.
Your entire post is garbage.
