Google has a translate service, when you select a URL to translate, a new page from Google will show up and display the original page translated. The new page have all URLs transformed so that, when you click it, it will show a translated version from the original page. This is just like what Sakhr [1] developed several years ago.

What is amazing is the translation languages includes Arabic, yes you can translate any page from Arabic to English and from English to Arabic. Have a look at http://translate.google.com/translate_t/

Also, when you search Google using an Arabic keywords, the search hits URL will have a link with the text: [Translate this page], click it to see it translated. Note that, the Arabic support is still in beta 😉

[1] You can see Sakhr Tarjum from http://translate.sakhr.com/, if you are in Egypt, you will not be allowed to view the page unless you are connected to Internet through dialup with the number 07770500! I don’t know what you will see from other countries.
