٣- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ خَالِدٍ الْبَرْقِيِّ عَنْ سَعْدِ بْنِ سَعْدٍ عَنْ أَبِي الْحَسَنِ (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ عَنْ قَوْمٍ يُصَغِّرُونَ الْقُفْزَانَ يَبِيعُونَ بِهَا قَالَ أُولَئِكَ الَّذِينَ يَبْخَسُونَ النَّاسَ أَشْيَاءَهُمْ. 
3. Muhammad ibn Yahya has narrated from Muhammad ibn Khalid al-Barqiy from Sa‘d ibn Sa‘d who has narrated the following: “I once asked abu al-Hassan , about a people who make al-Qufzan (measuring devices) small with which they sell. He (the Imam) said, ‘They are of the people who cause losses in their belongings.’”
