Going through my personal highlights of Arabs: A 3000 year history of peoples, tribes, and empires by Tim Mackintosh-Smith, with a focus on pre-Islamic / the ancient part. 

I do go off on a tangent on the Mongols (for comparisons sake). Dan Carlin's passionate and excellent account of their exploits can be found here:
