1- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ مَا كَانَ مِنْ طَعَامٍ سَمَّيْتَ فِيهِ كَيْلا فَلا يَصْلُحُ مُجَازَفَةً هَذَا مِمَّا يُكْرَهُ مِنْ بَيْعِ الطَّعَامِ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘In the case of foodstuff of known measurement venturous estimation is not valid and it is of undesirable matters in the case of foodstuff.”’
