4- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ مُثَنًّى الْحَنَّاطِ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ قُلْتُ لَهُ رَجُلٌ مِنْ نِيَّتِهِ الْوَفَاءُ وَهُوَ إِذَا كَالَ لَمْ يُحْسِنْ أَنْ يَكِيلَ قَالَ فَمَا يَقُولُ الَّذِينَ حَوْلَهُ قَالَ قُلْتُ يَقُولُونَ لا يُوفِي قَالَ هَذَا لا يَنْبَغِي لَهُ أَنْ يَكِيلَ.
4. Muhammad ibn Yahya narrated from Ahmad ibn Muhammad ibn Isa, from Ali ibn al-Hakam, from Muthanna al-Hannat, from some of our companions, from Abu Abdillah al-Sadiq 
, who said: "I said to him, 'A man has the intention of being honest, but when he measures, he does not know how to measure.' He said, 'What do those around him say?' I said, 'They say he does not fulfill (his measures).' He replied, 'This person should not measure.'"
