Al-Husayn ibn Sa’id, from Al-Qasim ibn Muhammad ibn Aban, from Zakkar ibn Farqad, from Uthman ibn Ziyad, who said: I said to Abu Ja’far عليه السلام: "I am in a state of travel, and I come across stagnant water while my hand is dirty. Can I dip it into the water?" Imam عليه السلام said: "There is no harm."
