Light can scatter (Rayleigh scattering, Thompson scattering), which does not involve an absorption/emission event (unless you are talking about resonant scattering for example in the Lyman Alpha line).
That's how clouds work. The albedo of clouds is very high, so little is absorbed. Nevertheless, the small water drops scatter the light.
