Chapter on Ritual Washings (Ghusl) and the Method of Performing Ghusl for Janabah (major impurity)

Al-Husayn bin Sa’eed, from Hammad, from Hariz, from Zurarah, Muhammad bin Muslim, and Abu Basir, from Abu Ja’far and Abu Abdullah عليه السلام, who said: Imam عليه السلام said: "The Messenger of Allah سبحانه وتعالى (may Allah سبحانه وتعالى bless him and his family) performed wudu with a mudd (a small measure) and performed ghusl with a sa' (a larger measure)." Then Imam عليه السلام said: "He صلى الله عليه وعلى آله وسلم and his wife performed ghusl with five mudds from a single container." Zurarah said: “I asked Imam عليه السلام, how did they do it?” Imam عليه السلام said: "He صلى الله عليه وعلى آله وسلم began by striking his hand with water before her and cleaned his private area, then she struck her hand and cleaned her private area. Then He صلى الله عليه وعلى آله وسلم poured water over himself, and she poured water over herself until they both finished. The amount with which the Messenger of Allah سبحانه وتعالى (may Allah سبحانه وتعالى bless him and his family) performed ghusl was three mudds, and the amount with which she performed ghusl was two mudds. It sufficed for both of them because they shared it together. However, if one performs ghusl alone, then a sa' is necessary."
