What is the issue with the Koran quote in Little Big World?

I read that the game is being delayed or recalled because someone found out that one of the songs used for background music in the game contains a quote from the Koran.

Is the game being recalled out of fear that non-Muslims will take offense at another religious text being quoted, or out of fear that Muslims will be offended at the Koran being used for non-religious purposes?

As a related question, is it a taboo in Islam to quote the Koran? Christians quote the Bible all the time, regardless of context…
