The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated from Abu al-Qasim Ja‘far ibn Muhammad, from his father, from Sa‘d ibn ‘Abdullah, from al-Munabbih ibn ‘Ubaydullah, from al-Husayn ibn ‘Alwan al-Kalbi, from ‘Amru ibn Khalid, from Zayd ibn ‘Ali, from his father, from his grandfather, from (Imam) Ali عليه السلام, who said: Imam Ali عليه السلام said: “I asked the Messenger of Allah سبحانه وتعالى (peace be upon him and his family) about a person in a state of janabah (major ritual impurity) and a menstruating woman who sweat in their clothes until the clothes stick to them.” He عليه السلام said: "Indeed, menstruation and janabah are where Allah سبحانه وتعالى, the Mighty and Majestic, has placed them. They are not in the sweat; therefore, they do not need to wash their clothes."
