Hadith 7332- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي نَجْرَانَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ مُحَمَّدِ بْنِ قَيْسٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) قَالَ قَضَى أَمِيرُ الْمُؤْمِنِينَ عَلِيٌّ (عَلَيْهِ السَّلام) فِي رَجُلٍ أَمَرَهُ نَفَرٌ لِيَبْتَاعَ لَهُمْ بَعِيراً بِنَقْدٍ وَيَزِيدُونَهُ فَوْقَ ذَلِكَ نَظِرَةً فَابْتَاعَ لَهُمْ بَعِيراً وَمَعَهُ بَعْضُهُمْ فَمَنَعَهُ أَنْ يَأْخُذَ مِنْهُمْ فَوْقَ وَرِقِهِ نَظِرَةً.
2. Ali ibn Ibrahim has narrated from his father from ibn abu Najran from ‘Asim ibn Hamid from Muhammad ibn Qays who has said the following: “Abu Ja‘far (a.s.), has said that ’Amir al-Mu’minin, Ali (a.s.), in the case of a man who was ordered by certain persons to ask to sell to them a camel and they had agreed to pay more if it was on credit with deferred payment, and he asked to sell to them a camel and certain ones of them were with him, judged to bar him from charging them more over the cash price with deferred payment.’”
