The Prophet ﷺ said, "Whoever pollinates date palms and then sells them, the fruits will belong to him unless the buyer stipulates that the fruits should belong to him (and the seller agrees).  

أَنَّ النَّبِيَّ ﷺ قَالَ أَيُّمَا امْرِئٍ أَبَّرَ نَخْلاً ثُمَّ بَاعَ أَصْلَهَا فَلِلَّذِي أَبَّرَ ثَمَرُ النَّخْلِ إِلاَّ أَنْ يَشْتَرِطَهُ الْمُبْتَاعُ
