Narrated by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, from Ahmad ibn Muhammad, from his father, from al-Husayn ibn al-Hasan ibn Aban, from al-Husayn ibn Sa'id, from Fadalah, from Hammad ibn Uthman, from Hakam ibn Hukaym, who said: I asked Abu Abdullah عليه السلام about the ghusl of janabah. Imam عليه السلام said: "Pour water onto your right hand and wash it, then wash off anything impure from your body, then wash your private parts. Pour water over your head and body, and perform your ghusl. If you are in a clean place, there is no harm if you do not wash your feet. However, if you are in a place that is not clean, then wash your feet." I said: "People say that one should perform wudu, like the wudu for prayer, before ghusl." Imam عليه السلام laughed and said: "What purification is more thorough and complete than ghusl?"
