I've heard from the one Muslim I know that they learn Arabic so they can read the Koran in its original tongue. Nothing is ever quite the same when translated, even though if translated properly (which is far from guaranteed with Bibles these days) it will give largely the same meaning.
That's why it's pretty typical for seminary students to learn a bit of koine Greek; so that they can gain a better understanding of the New Testament by reading it in the tongue it was written in. I don't think it's at all necessary to learn New Testament Greek to be a Christian, but it's very worthwhile.
