١٢- أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ بَعْضِ أَصْحَابِهِ عَنْ أَحْمَدَ بْنِ النَّضْرِ عَنْ عَمْرِو بْنِ شِمْرٍ عَنْ جَابِرٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ عَنِ السَّلَفِ فِي اللَّحْمِ قَالَ لا تَقْرَبَنَّهُ فَإِنَّهُ يُعْطِيكَ مَرَّةً السَّمِينَ وَمَرَّةً التَّاوِيَ وَمَرَّةً الْمَهْزُولَ اشْتَرِهِ مُعَايَنَةً يَداً بِيَدٍ قَالَ وَسَأَلْتُهُ عَنِ السَّلَفِ فِي رَوَايَا الْمَاءِ قَالَ لا تَقْرَبْهَا فَإِنَّهُ يُعْطِيكَ مَرَّةً نَاقِصَةً وَمَرَّةً كَامِلَةً وَلَكِنْ اشْتَرِهِ مُعَايَنَةً وَهُوَ أَسْلَمُ لَكَ وَلَهُ.
12. Abu Ali al-Ash’ariy has narrated from certain persons of his people from Ahmad ibn al-Nadr from ‘Amr ibn Shamir from Jabir who has said the following: “I once asked abu Ja‘far , about the case of advance payment for meat. He (the Imam) said, ‘You must not go close to it because one time he gives you fatty, one time what is about to become spoilled and one time he gives you boney. Buy with examination and in hand in hand manner.’ I then asked about advance payment for containers of water. He (the Imam) said, ‘You must not go close to it because one time he gives you less and one time complete. Buy it with examination; it is safe for you and for him.’”
