Narrated by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, from Abu al-Qasim Ja'far ibn Muhammad, from Muhammad ibn Ya'qub, from Ali ibn Ibrahim, from his father, from Hammad ibn Isa, from Hariz, from Zurara, who said: I said to Imam Abu Ja'far عليه السلام: "How does a person in a state of janabah (major ritual impurity) perform ghusl?" Imam عليه السلام said: "If no semen has touched his hand, he immerses it in water. Then he begins by cleaning his private parts, ensuring they are clean. After that, he pours water over his head three times, then over his right shoulder twice, and over his left shoulder twice. Whatever water flows over the body suffices."
