٧- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ أَبِي سَعِيدٍ الْمُكَارِي عَنْ عَبْدِ الْمَلِكِ بْنِ عَمْرٍو قَالَ قُلْتُ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَشْتَرِي الطَّعَامَ فَأَكْتَالُهُ وَمَعِي مَنْ قَدْ شَهِدَ الْكَيْلَ وَإِنَّمَا اكْتَلْتُهُ لِنَفْسِي فَيَقُولُ بِعْنِيهِ فَأَبِيعُهُ إِيَّاهُ بِذَلِكَ الْكَيْلِ الَّذِي كِلْتُهُ قَالَ لا بَأْسَ.
7. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan ibn Yahya from abu Sa‘id al-Mukariy from ‘Abd al-Malik ibn ‘Amr who has said the following: “This is concerning my question before abu ‘Abd Allah , about food that I buy and I measure it when someone witnesses my measuring but I measure it for myself. He then says, ‘Sell it to me.’ I then sell it to him by means of the same measurement that I made for myself. He (the Imam) said, ‘It is not harmful.”’
