10- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ
أَخْبَرَنِي مَنْ سَمِعَ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ سَأَلَهُ رَجُلٌ وَأَنَا عِنْدَهُ فَقَالَ لَهُ رَجُلٌ مُسْلِمٌ احْتَاجَ إِلَى بَيْعِ دَارِهِ فَمَشَى إِلَى أَخِيهِ فَقَالَ لَهُ أَبِيعُكَ دَارِي هَذِهِ وَتَكُونُ لَكَ أَحَبُّ إِلَيَّ مِنْ أَنْ تَكُونَ لِغَيْرِكَ عَلَى أَنْ تَشْتَرِطَ لِي إِنْ أَنَا جِئْتُكَ بِثَمَنِهَا إِلَى سَنَةٍ أَنْ تَرُدَّ عَلَيَّ فَقَالَ لا بَأْسَ بِهَذَا إِنْ جَاءَ بِثَمَنِهَا إِلَى سَنَةٍ رَدَّهَا عَلَيْهِ قُلْتُ فَإِنَّهَا كَانَتْ فِيهَا غَلَّةٌ كَثِيرَةٌ فَأَخَذَ الْغَلَّةَ لِمَنْ تَكُونُ فَقَالَ الْغَلَّةُ لِلْمُشْتَرِي أَلا تَرَى أَنَّهُ لَوِ احْتَرَقَتْ لَكَانَتْ مِنْ مَالِهِ.
10. Muhammad ibn Yahya has narrated from Muhammad ibn Al-Husayn from Safwan from Ishaq ibn ‘Ammar who has said the following: “One who had heard from abu ‘Abd Allah 
, informed me saying,
‘A man asked the Imam , when I was present. A Muslim man needed to sell his house and he went to his brother and said. “I want to sell this house to you because I like it to be with you instead of being with others, with one condition that if within a year I come back with money to pay you, return it back to me.’” He replied, ‘I agree. If you come back with payment within a year I will give it back to you.’ I further said, ‘This house had a certain amount of income. Who then can have the income?’ He (the Imam) replied, ‘Income belongs to the buyer; were it (the house) to burn down it would come from his property.’”
