When light scatters from a rough surface, it gets scattered in many different directions, and the surface can be considered as a collection of many small, relatively flat areas. The law of reflection applies to each of these areas individually, so the light will reflect off each area at the same angle that it impinges on it. Therefore, the law still holds but only for these small, flat areas of the surface.
