Allah (mohammad)lied. Mecca has been destroyed before, ancient arabian lore tells of a great flood, earthquakes, volcanic eruptions, huge lava flows. There are numerous impact craters on the Peninsula. Hundreds of thousands of square miles of sharp, burnt stones from meteor showers through which camel trains cannot pass. 'Allah' certainly seems to have tried his best to destroy Mecca - if I was an arab, I would be very careful...LOL!
