٢- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَنَّهُ قَالَ فِي الرَّجُلِ يَبْتَاعُ الطَّعَامَ ثُمَّ يَبِيعُهُ قَبْلَ أَنْ يُكَالَ قَالَ لا يَصْلُحُ لَهُ ذَلِكَ.
2. Ali ibn Ibrahim has narrated from his father and Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “About the case of a man who buys a certain amount of food then sells it without weighing or measurement, he (the Imam) said, ‘It is not a valid deal.’”
