I have only recently learned that The God Delusion was (unofficially) translated into Arabic by Bassam Al-Baghdadi, from Sweden. The PDF has been downloaded 10 million times with 30% of those downloads in Saudi Arabia.
I heard it in this talk between Matt Dillahunty and Richard Dawkins in Vancouver, Atheist Republic also write about it here.
An incredible statistic. Well done to Richard Dawkins and thanks to Bassam Al-Baghdadi!
