Narrated to me by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, through this chain of narration: from Sa'd, from Ahmad bin Muhammad, from Al-Husayn bin Sa'id, from his brother Al-Hasan, from Zur'ah bin Muhammad Al-Hadrami, from Sama'ah bin Mehran, from Abu Abdullah عليه السلام, who said: 'If a man is in a state of janabah (major ritual impurity) and places his hand into the vessel, there is no harm in it, provided that no semen has come into contact with his hand.'
