Lamb and Young Goats Fed with the Milk of Pigs

2. Humayd ibn Ziyad has narrated from ‘Abd Allah ibn Ahmad al-Nuhaykiy from Ibn Abi ‘Umayr from Bishr ibn Muslimah who has said the following: “About the case of a young goat that is fed with the milk of a pig and it is used to impregnate the flock of sheep, abu al-Hassan, al-Rida’ عليه السلام, has said, ‘It is like cheese. If you recognize its offspring exactly, then do not eat; but you can eat if you cannot recognize it.’”
