٤- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنِ ابْنِ مُسْكَانَ عَنْ سُلَيْمَانَ بْنِ خَالِدٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنِ الرَّجُلِ يُسْلِمُ فِي الزَّرْعِ فَيَأْخُذُ بَعْضَ طَعَامِهِ وَيَبْقَى بَعْضٌ لا يَجِدُ وَفَاءً فَيَعْرِضُ عَلَيْهِ صَاحِبُهُ رَأْسَ مَالِهِ قَالَ يَأْخُذُهُ فَإِنَّهُ حَلالٌ قُلْتُ فَإِنَّهُ يَبِيعُ مَا قَبَضَ مِنَ الطَّعَامِ فَيُضْعِفُ قَالَ وَإِنْ فَعَلَ فَإِنَّهُ حَلالٌ قَالَ وَسَأَلْتُهُ عَنْ رَجُلٍ يُسْلِمُ فِي غَيْرِ زَرْعٍ وَلا نَخْلٍ قَالَ يُسَمِّي شَيْئاً إِلَى أَجَلٍ مُسَمًّى.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali al-Nu’man from ibn Muskan from Sulayman ibn Khalid who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a man who makes advance payment for farms and takes a certain amount of his foodstuff and a certain amount remains. The other party offers him the remaining of his capital. He (the Imam) said, ‘He must accept it; it is lawful.’ I then said, ‘He sells his foodstuff that he has received and it doubles.’ He (the Imam) said, ‘If he does, it is lawful.’ I then asked him (the Imam) about a man who makes advance payment for what is not a farm or palm trees. He (the Imam) said, ‘He must name something for an appointed time.’”
