How to use 25mm 1.4 lens hood on 14mm 2.5
... and you'll see it lacks a hood bayonet therefore can only take screw on hoods (or filters). Since it doesn't suffer from flare and ghosts so there is not much to gain from fitting a hood on it anyway.
Other than that, as mentioned by a previous poster, hood shape and design varies according to the focal length therefore most chances the 25mm hood - even if you could find a way to fit it on (masking tape?) - would cause vignetting on the 14mm.
