[Machine] That a person lends in food with a specific price for a set period, as long as it is not in planting or fruit that has not shown its quality, the Sheikh said, "He means that Allah knows whether he lends it in its own planting or its own fruit, so it is not permissible because selling the fruit goods on top of the trees is only permissible when its quality is apparent."  

البيهقي:١١٠٨٦أَخْبَرَنَا أَبُو أَحْمَدَ الْمِهْرَجَانِيُّ أنبأ أَبُو بَكْرِ بْنُ جَعْفَرٍ ثنا مُحَمَّدُ بْنُ إِبْرَاهِيمَ ثنا ابْنُ بُكَيْرٍ ثنا مَالِكٌ عَنْ نَافِعٍ عَنْ عَبْدِ اللهِ بْنِ عُمَرَ أَنَّهُ قَالَ لَا بَأْسَ

بِأَنْ يُسْلِفَ الرَّجُلُ فِي الطَّعَامِ الْمَوْصُوفِ بِسِعْرٍ مَعْلُومٍ إِلَى أَجَلٍ مُسَمًّى مَا لَمْ يَكُنْ ذَلِكَ فِي زَرْعٍ لَمْ يَبْدُ صَلَاحُهُ أَوْ ثَمَرٍ لَمْ يَبْدُ صَلَاحُهُ قَالَ الشَّيْخُ يُرِيدُ بِهِ وَاللهُ أَعْلَمُ أَنْ يُسْلِفَهُ فِي زَرْعٍ بِعَيْنِهِ أَوْ ثَمَرٍ بِعَيْنِهِ فَلَا يَجُوزُ؛ لِأَنَّ بَيْعَ أَعْيَانِ الثِّمَارِ عَلَى رُءُوسِ الْأَشْجَارِ إِنَّمَا يَجُوزُ إِذَا بَدَا فِيهَا الصَّلَاحُ
