Abu Qatada reported the Prophet as saying, “The best type of horse is the black one with a blaze on its face and a white spot on its upper lip* next comes the horse with a blaze on its face and white on the legs, except on a right one. If it is not black, then a dark bay horse with those markings.”
* Artham. This may mean either that it has a white spot on its upper lip, or on the point of its nose.
Tirmidhi and Darimi transmitted it.
