Chapter on Purifying Clothes and Other Items From Impurities

The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Abu Al-Qasim Ja'far ibn Muhammad, from Muhammad ibn Ya'qub, from Muhammad ibn Yahya, from Al-Amraki ibn Ali, from Ali ibn Ja'far, from his brother Imam Musa ibn Ja'far عليه السلام. He said: I asked Imam عليه السلام about a man whose clothing is touched by a pig, and he does not wash it, then he remembers while praying - what should he do? Imam عليه السلام said: "If he has already started his prayer, then let him continue. But if he has not started his prayer, then he should sprinkle water on the affected area of his clothing unless it has left a mark, in which case he should wash it." And I asked Imam عليه السلام about a pig that drinks from a vessel - what should be done with it? Imam عليه السلام said: "It should be washed seven times."
