What are some sites that can teach me how to pronounce middle eastern names?

I'm doing research into the Taliban, Mujahideen, etc and, of course, this includes the individuals that they're comprised of. It's my belief that everything you know about someone amounts to nothing if you can't pronounce their name correctly. Some of them I can reason through, but some I just don't know how to say and I have no one to ask. I have no idea how to pronounce "Amir al-Mu'minin". Where can I find a book or a site or SOMETHING that will teach me? (I do plan on learning Arabic and Farsi when I graduate from high school in a few months, but for now.) Thanks.
