١٩- أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ صَالِحِ بْنِ أَبِي حَمَّادٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ حُذَيْفَةَ بْنِ مَنْصُورٍ عَنْ مُيَسِّرٍ قَالَ قُلْتُ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) إِنَّ عَامَّةَ مَنْ يَأْتِينِي مِنْ إِخْوَانِي فَحُدَّ لِي مِنْ مُعَامَلَتِهِمْ مَا لا أَجُوزُهُ إِلَى غَيْرِهِ فَقَالَ إِنْ وَلَّيْتَ أَخَاكَ فَحَسَنٌ وَإِلا فَبِعْ بَيْعَ الْبَصِيرِ الْمُدَاقِّ.
19. Ahmad ibn Muhammad has narrated from Salih ibn abu Hammad from Muhammad ibn Sinan from Hudhayfah ibn Mansur from Muyassir who has said the following: “I once said to abu ‘Abd Allah , ‘Most of my clients are from our brothers (in belief). I request you to set for me a limit, how should I deal with them in a transaction so that I will not go beyond that limit.’ He (the Imam) said, ‘If you consider your brother (in belief) as the person in charge it is fine, otherwise, deal with him in a transaction as one deals with a well aware hairsplitting person.”’
