3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ مُحَمَّدِ بْنِ الْفُضَيْلِ عَنْ أَبِي الصَّبَّاحِ الْكِنَانِيِّ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنْ لُحُومِ الأَضَاحِيِّ فَقَالَ كَانَ عَلِيُّ بْنُ الْحُسَيْنِ وَأَبُو جَعْفَرٍ (عَلَيْهِ السَّلاَم) يَتَصَدَّقَانِ بِثُلُثٍ عَلَى جِيرَانِهِمْ وَثُلُثٍ عَلَى السُّؤَّالِ وَثُلُثٌ يُمْسِكُونَهُ لأَهْلِ الْبَيْتِ.

3. A number of our people have narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Isma‘il from Muhammad ibn al-Fudayl from abu al-Sabbah al-Kinaniy who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the meat of offering animals. He (the Imam) said, ‘Ali ibn al-Husayn and abu Ja‘far, ‘Alayhim al-Salam, would give one-third as charity to their neighbors, one-third to those who ask and beg and kept one-third for their household.’”
