٤- الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ مُحَمَّدٍ قَالَ قَالَ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) إِنِّي أَكْرَهُ بَيْعَ عَشَرَةٍ بِأَحَدَ عَشَرَ وَعَشَرَةٍ بِاثْنَيْ عَشَرَ وَنَحْوَ ذَلِكَ مِنَ الْبَيْعِ وَلَكِنْ أَبِيعُكَ بِكَذَا وَكَذَا مُسَاوَمَةً قَالَ وَأَتَانِي مَتَاعٌ مِنْ مِصْرٍ فَكَرِهْتُ أَنْ أَبِيعَهُ كَذَلِكَ وَعَظُمَ عَلَيَّ فَبِعْتُهُ مُسَاوَمَةً.
4. Al-Husayn from Muhammad has narrated from Mu’alla’ ibn Muhammad from al-Hassan ibn Ali from Aban ibn ‘Uthman from Muhammad who has said the following: “Abu ‘Abd Allah , has said, ‘I do not like the sale of ten for eleven and ten for twelve and so on. I sell for so and so (fixed price) in the form of Musawamah (fixed price regardless of capital).’ He (the Imam) then said, ‘Once goods from Egypt came for me and I disliked selling it in that way ( Murabahah (capital plus profit)) and it seemed greatly heavy, so I sold it in the form of Musawamah (fixed price regardless of capital).”’
