عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنِ الْعَلَاءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا ( عليهما السلام ) قَالَ إِذَا دَخَلْتَ أَجَمَةً فَوَجَدْتَ بَيْضاً فَلَا تَأْكُلْ مِنْهُ إِلَّا مَا اخْتَلَفَ طَرَفَاهُ .
1. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I once asked one of the two Imam, (abu Ja‘far or abu ‘ Abd Allah), ‘Alayhim al-Salam, about the eggs that I may find in the wilderness. He (the Imam) said, ’Do not eat unless the shape of its both ends is different.’”
