٩- بَعْضُ أَصْحَابِنَا عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ أَبِي مَخْلَدٍ السَّرَّاجِ قَالَ كُنَّا عِنْدَ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) فَدَخَلَ عَلَيْهِ مُعَتِّبٌ فَقَالَ بِالْبَابِ رَجُلانِ فَقَالَ أَدْخِلْهُمَا فَدَخَلا فَقَالَ أَحَدُهُمَا إِنِّي رَجُلٌ قَصَّابٌ وَإِنِّي أَبِيعُ الْمُسُوكَ قَبْلَ أَنْ أَذْبَحَ الْغَنَمَ قَالَ لَيْسَ بِهِ بَأْسٌ وَلَكِنِ انْسُبْهَا غَنَمَ أَرْضِ كَذَا وَكَذَا. 
9. Certain persons of our people have narrated from Ali ibn Asbat from abu Mukhallad al-Sarraj who has said the following: “Once, we were with abu ‘Abd Allah , when Mu‘attib came in and said, ‘There are two people at the door.’ He (the Imam) said, ‘Bring them inside.’ The two men came inside and one of them said, ‘I am a butcher. Can I sell the skin before I slaughter the sheep?’ He (the Imam) said, ‘It is not unlawful. However, say from the sheep is from so and so land.’”
