Al Fadi and Dr Jay Smith  say that Mohammad received a revelation to change the direction of the qiblas from Jerusalem to Al Masjed Al Haram (Al Kaaba) in the year 624 AD.  They use Dan Gibson's research and conclude that the direction of the Qiblas in mosques between 624-706 AD were facing Petra.- The first mosque with the qibla facing Mecca was in 724 AD. This is a bad evidence for the S.I.N.  They also discuss the trade route theory by Dr Montgomery Watt who suggested the trade route  went  through Mecca to Gaza . He was trying to prove that Mecca was on the trade route. Dr Patricia Crone tried to prove that Mecca was never on the trade route which went through the red sea closer to the African coast and not the Arabian coast.
