1- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ مُحَمَّدِ بْنِ أَسْلَمَ عَنْ أَبِي حَمْزَةَ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَشْتَرِي الْمَتَاعَ جَمِيعاً بِالثَّمَنِ ثُمَّ يُقَوِّمُ كُلَّ ثَوْبٍ بِمَا يَسْوَى حَتَّى يَقَعَ عَلَى رَأْسِ مَالِهِ جَمِيعاً أَيَبِيعُهُ مُرَابَحَةً قَالَ لا حَتَّى يُبَيِّنَ لَهُ أَنَّمَا قَوَّمَهُ.
1. A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Muhammad ibn Aslam from abu Hamzah who has said the following: “I once asked abu Ja’far (a.s.), about the case of a man who buys goods altogether for a certain price, then sets a price for each piece proportionately until all of his capital is covered; if he can sell it in the form of Murabahah (capital plus a certain percent profit). He (the Imam) said, ‘No, he cannot do so until he makes it clear that the item has a fixed price.’”
