Chapter on Purifying Water From Impurities

The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad ibn Muhammad, from his father, from Muhammad ibn Al-Hasan, from Ahmad ibn Muhammad, from Al-Husayn ibn Sa'id, from Fadalah, from Aban ibn Uthman, from Abd Al-Rahman ibn Abi Abdullah. He said: I asked Abu Abdullah عليه السلام about a man who is touched by the urine of some animals. Should he wash it or not? Imam عليه السلام said: "He should wash the urine of a horse, a donkey, and a mule. But as for a sheep and any animal whose meat is permissible to eat, there is no harm in its urine."
