If this was indeed true why was there no outrage on the Scholars? this is just a Qiblah argument,and again,there needs to be some scholarly book,or something left which does indeed denote this view,the Quran doesn't even mention Petra,nor does it describe the enviroment of Petra,rather it describes a place with a cubic building,which is a sacred Mosque
Yet in Petra,it is not cubic,nor are there signs of Any mosques there
