Al-Husayn bin Sa‘id narrated from Yunus, from Ali bin Ri’ab, who said: I asked Abu Abdullah عليه السلام: "Are the ears considered part of the head?" Imam عليه السلام said: "Yes." I asked: "So if I wipe my head, should I wipe my ears as well?" Imam عليه السلام said: "Yes. It is as if I can see my father, with folds in the skin of his neck, who used to shave his head completely. It is as if I can see water flowing down his neck."
