٣- مُحَمَّدُ بْنُ يَحْيَى عَنْ بَعْضِ أَصْحَابِنَا عَنْ سِجَادَةَ عَنْ مُوسَى بْنِ بَكْرٍ قَالَ كُنَّا عِنْدَ أَبِي الْحَسَنِ (عَلَيْهِ السَّلام) فَإِذَا دَنَانِيرُ مَصْبُوبَةٌ بَيْنَ يَدَيْهِ فَنَظَرَ إِلَى دِينَارٍ فَأَخَذَهُ بِيَدِهِ ثُمَّ قَطَعَهُ بِنِصْفَيْنِ ثُمَّ قَالَ لِي أَلْقِهِ فِي الْبَالُوعَةِ حَتَّى لا يُبَاعَ شَيْ‏ءٌ فِيهِ غِشٌّ.
3. Muhammad ibn Yahya has narrated from certain persons of our people from Sajdah from Musa ibn Bukayr who has said the following: “Once we were in the presence of abu al-Hassan , while in front of him there were certain pieces of dinars. He (the Imam) looked at one piece and picked it up and broke it into two pieces. He (the Imam) said to me, ‘Throw it in the trash so an adulterated thing is not purchased anymore.’”
