Narrated by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad ibn Muhammad, from his father, from al-Husayn ibn al-Hasan ibn Aban, from al-Husayn ibn Sa'id, from al-Nadr ibn Suwayd, from Ibn Sinan, from Abu Abdullah عليه السلام, who said: Imam عليه السلام said: “The ghusl (ritual bath) is prescribed for janabah, on Fridays, on the Day of Eid al-Fitr, on the Day of Eid al-Adha, on the Day of Arafah at the time of midday, for one who washes a deceased person, at the time of entering ihram, upon entering Mecca and Medina, upon entering the Kaaba, for the visitations (ziyarah), and on the three nights of the month of Ramadan."
