The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad bin Muhammad, from his father, from Sa‘d bin Abdullah, from Musa bin Ja‘far, from Wahb, from Al-Hasan bin Ali Al-Washsha’, from Khalaf bin Hammad, from someone who narrated to him from Abu Abdullah عليه السلام, who said: I asked Imam عليه السلام: "What should a person do if he forgets to wipe his head whilst already in prayer?" Imam عليه السلام said: "If there is moisture in his beard, he should wipe with that." I asked: "What if he does not have a beard?" Imam عليه السلام replied: "Then he should wipe from his eyebrows or the lashes of his eyes."
