2. Hammad has narrated from Hariz from Muhammad ibn Muslim who has said the following: “I once asked abu ’Abd Allah عليه السلام, about the milk of camels, sheep and cows and their urine and their meat. He (the Imam) said, ‘You must not take Wudu’ with the water which is mixed with any of such items. You do not need to wash if your clothes come in contact with such items unless it is for removing stains.’ He (the narrator) said that I then asked about the urine of animals, such as mules and donkeys. He (the Imam) said, ‘You must wash it clean but if you do not know the polluted area, wash all of the clothes, and if you have doubts then just pour water to wash it clean.’”
