Mihrabs were there since the past,give me one ancient islamic literature mentioning petra.
The Abbasids burned many libraries and went through extensive lengths to destroy any fragment of Quranic history from Petra, then they manufactured your religion thereafter. That's the dominant theory, which you can learn from Dan Gibson's documentary.
If you are overly emotional about your religion, then don't watch it.
Again, that doesn't prove us anything.
What type of books were burned by Muslim empires?
Obviously, stupid scientists couldn't read these books because they already burned, so how did they know these books mentioned about Petra? They are lying.
So, how do you know that these books mentioned about Petra for Muhammad's birth? Show your evidence.
Maybe these books were written by infidels, or Shi'ite or hypocrites.
Sorry NWO, but your evidence is not powerful enough to support your claim.
So there is no good evidence that these books mentioned about Muhammad's birth in Petra because they were already burned.
According to sources, Islamic invaders burned mass libraries that were belonged to infidels. Just like Muhammad destroyed idols in Mecca.
Some researches suggested that Caliph Umar also burned libraries in Alexandria, Egypt.
