2- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ الْوَشَّاءِ عَنْ عَاصِمِ بْنِ حُمَيْدٍ قَالَ قَالَ لِي أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَيَّ شَيْ‏ءٍ تُعَالِجُ قُلْتُ أَبِيعُ الطَّعَامَ فَقَالَ لِي اشْتَرِ الْجَيِّدَ وَبِعِ الْجَيِّدَ فَإِنَّ الْجَيِّدَ إِذَا بِعْتَهُ قِيلَ لَهُ بَارَكَ اللهُ فِيكَ وَفِيمَنْ بَاعَكَ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ya’qub ibn Yazid from al-Washsha’ from ‘Asem ibn Hamid who has said the following: “Once, abu ‘Abd Allah (a.s.), asked me, ‘How do you make a living?’ I replied, ‘I sell foodstuff.’ He (the Imam) said to me, ‘Buy those of good quality and sell of the good quality; if you sell that of good quality it is said, “Allah places blessings in you and the one who sold to you.’””
