Provide a link to your arabian forums so we can take a look? Talking off-hand, I would say that the low earning is due to the traffic extraction and your niche/topic might not be the best too.
to get higher CPC you need to have google ads that are targeted for more expensive keywords. For example an ad that is shown for the keyword "weight loss" has a much higher CPC than an ad thsat is shown for the keyword "arabian songs download" (just from the top of my head) . Try to put some articles wich are optimized for keywords with higer CPC. Good luck!
Sorry, it is hard to get good CPC from non-english site. The only way is change your arab language forum to english forum
