It was narrated from Salim, from his father that the Prophet said: "Whoever buys a date-palm tree after it has been pollinated, its fruits belong to the seller, unless the purchaser has stipulated otherwise.

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ مَنِ ابْتَاعَ نَخْلاً بَعْدَ أَنْ تُؤَبَّرَ فَثَمَرَتُهَا لِلْبَائِعِ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَمَنْ بَاعَ عَبْدًا وَلَهُ مَالٌ فَمَالُهُ لِلْبَائِعِ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ ‏" ‏ ‏.‏
