No problem!
Maybe he thought that you would be able to offer a 'pop up' on the website for Arabic readers
If i go on a Spanish website, my computer will offer to "translate" it for me.
Maybe this is what he thought you would do, instead of provide a link to another website for the translation.
Obviously he wants to keep people and traffic on his own website. This is understandable. But, after getting the translation done, he may as well now link to it.
