Narrated by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me: He said that Ahmad ibn Muhammad narrated from his father, from al-Husayn ibn al-Hasan ibn Aban, from al-Husayn ibn Sa'id, from al-Qasim ibn Urwah, from Abdul Hamid, from Muhammad ibn Muslim, from Abu Ja'far عليه السلام, who said: Imam عليه السلام said: "The ghusl (ritual bath) is prescribed for janabah, for Friday, for the two Eids, on the Day of Arafah, on three nights in the month of Ramadan, when you enter the Haram (Sacred Precinct), when you intend to enter the Mosque of the Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family), and for one who has washed a deceased person."
