Unless http://en.wikipedia.beta.wmflabs.org/wiki/Special:SiteMatrix is wrong, we don't have any arab wiki on beta. Please set up one and import some content, so that things like bug 47810 can be tested.
Arab Wikisource may be a good choice of a wiki to import to have many pages without too much history and with (perhaps) a variety of styles.
