:I'm not sure what version you're referring to but the current version  seems fine to me. It adequetly sumarises the Muslim POV from what I can see "They do not regard Muhammad as the founder of a new religion, but as the restorer of the original monotheistic faith of Abraham, Moses, Jesus, and other prophets.". If this isn't sufficient for you, I believe the issue was discussed in the Muhammad article and the discussion there may be useful for consideration here.
