The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, informed me from Ahmad ibn Muhammad, from his father, from al-Husayn ibn al-Hasan ibn Aban, from al-Husayn ibn Saʿid, from Ṣafwan and Fadalah ibn Ayyub, from Fudayl ibn ʿUthman, from Abu ʿUbaydah al-Hadhdhaʾ, who said: I assisted Abu Jaʿfar عليه السلام in performing ablution at Jamʿ (Muzdalifah) after he had relieved himself. I handed Imam عليه السلام water, and He عليه السلام cleansed himself (Istinjaʾ). Then He عليه السلام took a handful of water and washed his face, another handful and washed his right arm, and another handful and washed his left arm. Then, with the remaining moisture, He عليه السلام wiped his head and his feet."
