Ahmad bin Muhammad bin ‘Isa narrated from Mu‘ammar bin Khallad, who said: I asked Abu Al-Hasan عليه السلام: "Is it sufficient for a man to wipe his feet with the remaining moisture from his head?" Imam عليه السلام replied: "With the moisture from his head, no." So I asked: "With fresh water?" Imam عليه السلام replied, "With the moisture from his head, yes."
