Neither actually..it was popular in both Persia and India before the Arabs played chess. Additionally, the so-called Arabic numeral system was an invention of the Hindus in ancient India. The Ababs borrowed it it and later popularized it in Europe during the Muslim rule in Spain.

Honestly, I can't think of a single thing that Arabs invented. This PC exhibition is just a joke!!

Look here for a synopsis of several of these inventions. http://news.independent.co.uk/world/science_technology/article350594.ece

If you look at the story behind the invention and remove the fluff, you can almost see the truth.

From the site:

Did you know that the basic scale in music today comes from Arabic syllables do, re, mi, fa, sol, la and ti? The Arabic alphabet for these notes is Dal-Ra-Mim-Fa-Sad-Lam-Sin.

and blatantly false. The Solfeggio system was created about the 100 by Guido De Arrezo and the syllables from from a hymn called 'Ut queant laxis'. That other cultures used other syllables for other notes has nothing to do with the system still in use today.
