قَالَ مَالِكٌ : وَالْأَمْرُ عِنْدَنَا فِي بَيْعِ الْبِطِّيخِ، وَالْقِثَّاءِ، وَالْخِرْبِزِ، وَالْجَزَرِ إِنَّ بَيْعَهُ إِذَا بَدَا صَلَاحُهُ حَلَالٌ جَائِزٌ، ثُمَّ يَكُونُ لِلْمُشْتَرِي مَا يَنْبُتُ حَتَّى يَنْقَطِعَ ثَمَرُهُ وَيَهْلِكَ، وَلَيْسَ فِي ذَلِكَ وَقْتٌ يُؤَقَّتُ، وَذَلِكَ أَنَّ وَقْتَهُ مَعْرُوفٌ عِنْدَ النَّاسِ، وَرُبَّمَا دَخَلَتْهُ الْعَاهَةُ، فَقَطَعَتْ ثَمَرَتَهُ قَبْلَ أَنْ يَأْتِيَ ذَلِكَ الْوَقْتُ، فَإِذَا دَخَلَتْهُ الْعَاهَةُ بِجَائِحَةٍ تَبْلُغُ الثُّلُثَ فَصَاعِدًا، كَانَ ذَلِكَ مَوْضُوعًا عَنِ الَّذِي ابْتَاعَهُ
Imam Malik, may Allah have mercy on him, said that it is permissible to sell melon, cucumber, and carrot when their quality is known. Then whatever grows will belong to the buyer until the crop is finished. There is no fixed time for this; the ruling will be according to the custom and practice of each place. If, before that time, due to some calamity, there is a loss up to one third of the goods, then that loss will be compensated to the buyer. And if the loss is less than one third, then no compensation will be given.
