Hadith 1402B6

قَالَ مَالِكٌ : وَإِنَّمَا ذَلِكَ بِمَنْزِلَةِ أَنْ يَقُولَ رَبُّ الْحَائِطِ لِرَجُلٍ مِنَ النَّاسِ : ابْنِ لِي هَاهُنَا بَيْتًا. أَوِ احْفِرْ لِي بِئْرًا. أَوْ أَجْرِ لِي عَيْنًا، أَوِ اعْمَلْ لِي عَمَلًا بِنِصْفِ ثَمَرِ حَائِطِي هَذَا قَبْلَ أَنْ يَطِيبَ ثَمَرُ الْحَائِطِ، وَيَحِلَّ بَيْعُهُ. فَهَذَا بَيْعُ الثَّمَرِ قَبْلَ أَنْ يَبْدُوَ صَلَاحُهُ. وَقَدْ نَهَى رَسُولُ اللّٰهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ عَنْ بَيْعِ الثِّمَارِ حَتَّى يَبْدُوَ صَلَاحُهَا.
Imam Malik, may Allah have mercy on him, said: Its example is like that of a garden owner who says to someone: Build a house for me, or dig a well, or repair a spring, or do something else, and in exchange I will give you half of the fruits of my garden, even though those fruits have not yet ripened, nor is their quality known. This is not permissible because it is a sale of fruits before their quality is known, and the Messenger of Allah, peace and blessings be upon him, forbade this. Imam Malik, may Allah have mercy on him, said: If the fruits have appeared well and their quality is assured, then if someone does any of these works in exchange for those fruits, there is no harm in it.
