Muslims believe that God sent many prophets carrying divine teachings to all nations, and that Jesus was amongst those. They believe in one almighty, perfect God, not one that can be reduced to the shape of a bipedal animal, and thus reject the 3-in-1-in-3 mumbo jumbo that post-Jesus crowds came up with.

As you rightly stated, they also believe that Jesus was raised/saved by God, who replaced him with a lookalike, and that lookalike was crucified. They believe that Jesus shall return.
