Does that include spaces. Do you want everything past the first
space to be passed to "mut" in one single argument?

you could do something like:

alias mut=':;#'
setopt interactivecomments
check-for-mut() {
  if [[ $1 = "mut "* ]]; then
    command mut "${1#mut }"
  fi
}
preexec_functions+=(check-for-mut)

(not tested).

Alternatively, you could redefine the accept-line widget so that
it inserts quotes were needed.

accept-line() {
  if [[ $BUFFER = "mut "* ]]; then
    BUFFER="mut ${(qq)BUFFER#mut }"
  fi
  zle .accept-line
}
zle -N accept-line
