Mishkat al-Masabih 13:43

He reported God’s Messenger as saying, “The fingers and toes are equal, the teeth are equal, the front tooth and the molar tooth are equal, this and that are equal.” Abu Dawud transmitted it. 1. In this tradition only al-asabi' is given, whereas the asabi of the hands and the feet are specified in the preceding. It must obviously mean both fingers and toes here. 2. It has been suggested that "this and that” refers only to the little finger and the thumb (cf. the first tradition in the chapter), but it may here refer to the front tooth and the molar tooth mentioned immediately before it.
