Muhammad ibn Isma'il reported from Al-Fadl ibn Shadhan, from Ibn Abi Umayr, from Mu'awiyah ibn Ammar, who said: I asked Abu Abdillah عليه السلام about a menstruating woman handing water to a man. Imam عليه السلام replied: "Some of the wives of the Prophet صلى الله عليه وعلى آله وسلم used to pour water for Him صلى الله عليه وعلى آله وسلم while they were menstruating and would hand Him صلى الله عليه وعلى آله وسلم the prayer mat."
