Narrator:Abdullāh ibn ‘Umar
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ
" أَيُّمَا امْرِئٍ أَبَّرَ نَخْلاً ثُمَّ بَاعَ أَصْلَهَا فَلِلَّذِي أَبَّرَ ثَمَرُ النَّخْلِ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ "
It was narrated from Ibn 'Umar that the Prophet said:
"Any man who pollinates a date-palm tree then sells it, the fruits of the tree are for the one who pollinated it, unless the purchaser stipulated otherwise."
