١١- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ قُلْتُ لأبِي الْحَسَنِ (عَلَيْهِ السَّلام) يَكُونُ لِي عَلَى الرَّجُلِ دَرَاهِمُ فَيَقُولُ أَخِّرْنِي بِهَا وَأَنَا أُرْبِحُكَ فَأَبِيعُهُ جُبَّةً تُقَوَّمُ عَلَيَّ بِأَلْفِ دِرْهَمٍ بِعَشَرَةِ آلافِ دِرْهَمٍ أَوْ قَالَ بِعِشْرِينَ أَلْفاً وَأُؤَخِّرُهُ بِالْمَالِ قَالَ لا بَأْسَ.
11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibn Abi ‘Umayr from Muhammad ibn Ishaq ibn ‘Ammar who has said the following: “I once asked abu al-Hassan , about the case of a man who owes me a certain amount of dirham and says to me, ‘Extend the payback time and I will give you profit’. I then sell to him a gown worth a thousand dirham for ten thousand dirhams - or that he said, twenty thousand dirhams - and extend the payback time. He (the Imam) said, ‘It is not unlawful.’”
