Muwatta Imam Malik Book of Business Transactions, Hadith 9
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ said, "If palm trees are sold after they have been pollinated, the fruit belongs to the seller unless the buyer makes a stipulation about its inclusion."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " مَنْ بَاعَ نَخْلاً قَدْ أُبِّرَتْ فَثَمَرُهَا لِلْبَائِعِ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ " .
