حُمَيْدُ بْنُ زِيَادٍ عَنْ عَبْدِ اللَّهِ بْنِ أَحْمَدَ النَّهِيكِيِّ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ بِشْرِ بْنِ مَسْلَمَةَ عَنْ أَبِي الْحَسَنِ الرِّضَا ( عليه السلام ) فِي جَدْيٍ يَرْضِعُ مِنْ خِنْزِيرَةٍ ثُمَّ ضَرَبَ فِي الْغَنَمِ قَالَ هُوَ بِمَنْزِلَةِ الْجُبُنِّ فَمَا عَرَفْتَ بِأَنَّهُ ضَرَبَهُ فَلَا تَأْكُلْهُ وَ مَا لَمْ تَعْرِفْهُ فَكُلْهُ .
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’ (a.s.), 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.’”
