4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Khalid from al-Qasim ibn Muhammad ibn ‘Urwah from Bukayr ibn ’A‘yan from Zurarah who has said the following: “One of the two Imam, ‘Alayhim al-Salam, about the urine of edible animals that pollutes clothes, expressed dislike. I said, ‘It is from an edible animal.’ He (the Imam) said, ‘It is true but Allah has not made it for eating.’”
