3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلاءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنِ الْبَدَنَةِ تُنْتَجُ أَ نَحْلُبُهَا قَالَ احْلُبْهَا حَلْباً غَيْرَ مُضِرٍّ بِالْوَلَدِ ثُمَّ انْحَرْهُمَا جَمِيعاً قُلْتُ يَشْرَبُ مِنْ لَبَنِهَا قَالَ نَعَمْ وَيَسْقِي إِنْ شَاءَ.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I once asked abu Ja‘far (a.s.), about the case of a badanah that gives birth; if it is permissible to milk it. He (the Imam) said, ‘You can milk it without harming its young. You then can slaughter both of them.’ I asked, ‘Can its milk be used for drinking?’ He (the Imam) said, ‘Yes, you can do so and give to others.’”
