٣- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَبَانٍ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَشْتَرِي مِنَ الْعَامِلِ وَهُوَ يَظْلِمُ قَالَ يَشْتَرِي مِنْهُ مَا لَمْ يَعْلَمْ أَنَّهُ ظَلَمَ فِيهِ أَحَداً.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Ali from Aban from Ishaq ibn ‘Ammar who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a man who bought from a charity collector who committed injustice. He (the Imam) said, ‘He can buy from him unless he learns that he has done injustice in collecting those goods.’”
