Sorry mate i dunno what you're talking about as me and the vast majority of Christians have never even heard of Petra, wasn't she the Blue Peter dog or something?
Anyway the bottom line is that Mohammed came out of a cave and said "The angel Gabriel just spoke to me", so why should anybody believe him?
en.wikipedia.org
christians online were obsessed with this theory that the real mecca was in petra and that at some point some arabs altered it all for some type of insane magical reason.
As for what Mohammad said...
i can go in depth on that one but i question your sincerity..
you've refused to even acknowledge themes in the bible that would naturally lead to a gentile prophet
for example...
Paul argued that the christians in his time were akin tot he Patirarchs of judaism,
just ponder that..they were like Abraham, Isaac, Jacob. Righteous by faith, without the law.
YET God saw fit to give the israelites the law through Moses. Paul explained that the israelites lost true belief in egypt..
you yourself agree that Jesus is not God..yet this is christian theology now.
so if God could bring the law to israelites, moreso for Jesus to 'fulfill' later down the line, doesnt it make Jesus greater if he returns and fulfills a law that's for all people and not just jews?
it makes sense that the gentiles lost the way through the trinitiarian doctrine and pagan ideas of the roman church, which subsequently opened the path for a gentile prophet. Esp given that God made promises to Hagar and Abraham about Ismael that also had to be fulfilled before the second coming of Jesus Christ.
those are just some reasons why islam is evidently the true religion.
I've already shown you that Revelation 11's 1260 days prophecy of the gentiles (in prophecy, day=yr too).
it said the gentiles would trample on the outer court on the temple mount for 1260 days
as it happens the al jami al aqsa (the mosque on the temple mount) is at the outer court part...
and it just happens that muslims ruled Jerusalem for exactly 1260 lunar yrs
Muslims conquered Jerusalem in
637AD
first crusade where it was lost to Christians..
1099AD
Muslims took it back in 1187 and held it till 1948. 761 years and 462 years
Total 1223 years of Muslim rule.
In lunar years that is 1223 X 1.03068
That comes to exactly 1260 years.
what im saying only lends credibility and fulfillment to biblical prophecies..
in the parable of tenants Jesus said the vineyard (isaiah 5, refers to Jerusalem) to another people who would produce the fruits.
Muslims held jerusalem longer than jews and christians.
