"Whoever buys a palm tree that has been pollinated, its fruits belong to the seller, unless the purchaser stipulated a condition." (Sahih) Another chain from Ibn 'Umar, from the Prophet ﷺ, with similar wording.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنِ اشْتَرَى نَخْلاً قَدْ أُبِّرَتْ فَثَمَرَتُهَا لِلْبَائِعِ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ بِنَحْوِهِ  

the Messenger of Allah ﷺ said: "Whoever sells a palm tree that has been pollinated, its fruits belong to the seller, unless the purchaser stipulated a condition. And whoever buys a slave who has wealth, his wealth belongs to the seller, unless the purchaser stipulated a condition."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ بَاعَ نَخْلاً قَدْ أُبِّرَتْ فَثَمَرَتُهَا لِلَّذِي بَاعَهَا إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَمَنِ ابْتَاعَ عَبْدًا وَلَهُ مَالٌ فَمَالُهُ لِلَّذِي بَاعَهُ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ  

"Whoever sells a palm tree and sells a slave." Mentioning both of them together.[1]  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ مَنْ بَاعَ نَخْلاً وَبَاعَ عَبْدًا جَمَعَهُمَا جَمِيعًا  

"The Messenger of Allah ﷺ ruled that the fruit of a palm tree belongs to the one who pollinated it, and that the wealth of a slave belongs to the one who sold him, unless the purchaser stipulated a condition."  

قَضَى رَسُولُ اللَّهِ ﷺ أَنَّ ثَمَرَ النَّخْلِ لِمَنْ أَبَّرَهَا إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَأَنَّ مَالَ الْمَمْلُوكِ لِمَنْ بَاعَهُ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ
