Well the ONLY way anyone this side of the cross gets to heaven is through Jesus Christ.
John 14:6

I am the way, the truth and the life NO ONE comes to the Father but by ME. ( Jesus said this)

The ten comandments cannot be kept by fallen man so they have NOTHING to do with salvation. ALL they do is make us realize we CAN'T get to heaven by good works.

Yes, a muslim can go to heaven. He just needs to confess Jesus IS LORD. This is according to the Bible and. I have no other authority as a Christian. That is what the Bible says.
