مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنْ أَحْمَدَ بْنِ الْمُبَارَكِ عَنْ صَالِحِ بْنِ أَعْيَنَ عَنِ الْوَشَّاءِ عَنْ أَيُّوبَ بْنِ أَعْيَنَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قُلْتُ لَهُ جُعِلْتُ فِدَاكَ مَا تَقُولُ فِي حَيَّةٍ ابْتَلَعَتْ سَمَكَةً ثُمَّ طَرَحَتْهَا وَ هِيَ حَيَّةٌ تَضْطَرِبُ أَ فَآكُلُهَا فَقَالَ ( عليه السلام ) إِنْ كَانَتْ فُلُوسُهَا قَدْ تَسَلَّخَتْ فَلَا تَأْكُلْهَا وَ إِنْ كَانَتْ لَمْ تَتَسَلَّخْ فَكُلْهَا .
16. Muhammad ibn Yahya has narrated, from Ahmad ibn Muhammad, from Ya‘qub ibn Yazid from Ahmad ibn al-Mubarak, from Salih ibn ‘A‘yan from al-Washsha’ from Ayyub ibn ‘A‘yan who has said the following: “I once said to abu ‘Abd Allah , I pray to Allah to keep my soul in service for your cause. What do you say about a snake that has swallowed a fish then has thrown it out and it still is alive and struggling; if it can be used for food. He (the Imam) said, ‘If its scales are peeled off then do not use it for food; but if it is not peeled off you can use it for food.’”
