٦- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ حَنَانِ بْنِ سَدِيرٍ قَالَ كُنْتُ عِنْدَ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) فَقَالَ لَهُ جَعْفَرُ بْنُ حَنَانٍ مَا تَقُولُ فِي الْعِينَةِ فِي رَجُلٍ يُبَايِعُ رَجُلا فَيَقُولُ لَهُ أُبَايِعُكَ بِدَهْ دَوَازْدَهْ وَبِدَهْ يَازْدَهْ فَقَالَ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) هَذَا فَاسِدٌ وَلَكِنْ يَقُولُ أَرْبَحُ عَلَيْكَ فِي جَمِيعِ الدَّرَاهِمِ كَذَا وَكَذَا وَيُسَاوِمُهُ عَلَى هَذَا فَلَيْسَ بِهِ بَأْسٌ وَقَالَ أُسَاوِمُهُ وَلَيْسَ عِنْدِي مَتَاعٌ قَالَ لا بَأْسَ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Hanan ibn Sadir who has said the following: “Once I was with abu ‘Abd Allah , when Ja’far ibn Hanan asked him (the Imam), ‘What do you say about al- ’Aynah in the case of a man who sells certain goods to a man and says, “I sell to you bah dah dawazdah and bah dahyazdahT” Abu ‘Abd Allah , said, ‘This is not valid. He must, however, say, “For all dirhams I give you so and so amount of dirham profit in the form of Musawamah (fixed price regardless of capital) in this deal;” then it is not unlawful.’ He then asked, ‘Can I make a deal in the form of Musawamah (fixed price regardless of capital) and I do not have any assets?’ He (the Imam) said, ‘It is not unlawful.’”
