مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ مُوسَى عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ ابْنِ فَضَّالٍ عَنْ بَعْضِ أَصْحَابِنَا عَنِ ابْنِ أَبِي يَعْفُورٍ قَالَ قُلْتُ لِأَبِي عَبْدِ اللَّهِ ( عليه السلام ) إِنَّ الدَّجَاجَةَ تَكُونُ فِي الْمَنْزِلِ وَ لَيْسَ مَعَهَا دِيكٌ تَعْتَلِفُ مِنَ الْكُنَاسَةِ وَ غَيْرِهَا وَ تَبِيضُ مِنْ غَيْرِ أَنْ يَرْكَبَهَا الدِّيكُ فَمَا تَقُولُ فِي أَكْلِ ذَلِكَ الْبَيْضِ فَقَالَ لِي إِنَّ الْبَيْضَ إِذَا كَانَ مِمَّا يُؤْكَلُ لَحْمُهُ فَلَا بَأْسَ بِهِ وَ بِأَكْلِهِ وَ هُوَ حَلَالٌ.
6. Muhammad ibn Yahya has narrated from Muhammad ibn Musa from Ya‘qub ibn Yazid from ibn Faddal from certain persons of our people from ibn abu Ya‘fur who has said the following: “I once said to abu ‘Abd Allah , that a domestic hen without a roster feeds on dump site and so on and gives eggs without mating with a rooster. ‘What do you say about such an egg and if such egg is edible? He (the Imam) said to me, ‘If such egg is from an edible bird it is not unlawful and eating it is permissible.’”
