You left out Egypt, Persia, Japan. Perhaps a course in the early trade routes would be beneficial to your ignert racist azz. Here's an EZ guide to get started

I specifically mentioned trade routes, dumb azz.  It's like I bring it up and you act like I didn't and try to take credit for mentioning its previous importance. 

I also said most.  Japan is an exception.  I commend them.  The Muslim worlds golden age ended with the renaissance... look it up.  It's almost exact to the date.  The Islamic world was good at preserving knowledge from the ancient world and the Arabic number system was good, but it never achieved anything close to what Rome did. 

The Islamic world flourished mostly due to over land trade routes and the fact that the Roman Empire fell.  Once Europe recovered they returned to their backward state.  Not even oil can save most Muslim nations except tiny Emirates.
