From him, from Muhammad ibn Al-Husayn, from Ibn Abi Umair, from some of our companions - and I believe it was Hafs ibn Al-Bukhtari - who said: It was said to Abu Abdullah عليه السلام regarding dough that was kneaded with impure water -what should be done with it? Imam عليه السلام said: "It should be sold to someone who considers eating carrion permissible."
