Narrated 'Abdullah (ra) said, I heard the Messenger of Allah ﷺ say "If somebody buys date-palms after they have been pollinated, the fruits will belong to the seller unless the buyer stipulates the contrary. If somebody buys a slave having some property, the property will belong to the seller unless the buyer stipulate that it should belong to him."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنِ ابْتَاعَ نَخْلاً بَعْدَ أَنْ تُؤَبَّرَ فَثَمَرَتُهَا لِلْبَائِعِ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَمَنِ ابْتَاعَ عَبْدًا وَلَهُ مَالٌ فَمَالُهُ لِلَّذِي بَاعَهُ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَعَنْ مَالِكٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنْ عُمَرَ فِي الْعَبْدِ  

The Prophet ﷺ permitted selling the dates of the 'Araya for ready dates by estimating the amount of the former (as they are still on the trees).  

رَخَّصَ النَّبِيُّ ﷺ أَنْ تُبَاعَ الْعَرَايَا بِخَرْصِهَا تَمْرًا  

The Prophet ﷺ forbade the sales called Al-Mukhabara, Al-Muhaqala and Al-Muzabana and the selling of fruits till they are free from blights. He forbade the selling of the fruits except for money, except the 'Araya.  

سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ ؓ نَهَى النَّبِيُّ ﷺ عَنِ الْمُخَابَرَةِ وَالْمُحَاقَلَةِ وَعَنِ الْمُزَابَنَةِ وَعَنْ بَيْعِ الثَّمَرِ حَتَّى يَبْدُوَ صَلاَحُهَا وَأَنْ لاَ تُبَاعَ إِلاَّ بِالدِّينَارِ وَالدِّرْهَمِ إِلاَّ الْعَرَايَا  

The Prophet ﷺ allowed the sale of the dates of the 'Araya for ready dates by estimating the former which should be estimated as less than five Awsuq or five Awsuq. (Dawud, the sub-narrator is not sure as to the right amount.)  

رَخَّصَ النَّبِيُّ ﷺ فِي بَيْعِ الْعَرَايَا بِخَرْصِهَا مِنَ التَّمْرِ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ أَوْ فِي خَمْسَةِ أَوْسُقٍ شَكَّ دَاوُدُ فِي ذَلِكَ  

Messenger of Allah ﷺ forbade the sale of Muzabana, i.e. selling of fruits for fruits, except in the case of 'Araya; he allowed the owners of 'Araya such kind of sale.  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ الْمُزَابَنَةِ بَيْعِ الثَّمَرِ بِالتَّمْرِ إِلاَّ أَصْحَابَ الْعَرَايَا فَإِنَّهُ أَذِنَ لَهُمْ قَالَ أَبُو عَبْدِ اللَّهِ وَقَالَ ابْنُ إِسْحَاقَ حَدَّثَنِي بُشَيْرٌ مِثْلَهُ
