It is forbidden to draw and digitally alter complete images of living beings. As for incomplete images, such as drawing only the head and chest, some scholars have permitted it, like the Maliki, Hanbali, and Shafi'i schools, provided the deficiency is in the visible limbs without which the animal cannot survive, or if it is headless. Some scholars believe that drawing a head alone without a body is forbidden, although staying further away from doubt is safer. Images must not be used to mock others.
