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 " .
“Whoever buys a date-palm tree after it has been pollinated, its fruits belong to the seller, unless the purchaser has stipulated otherwise. And whoever buys a slave who has wealth, his wealth belongs to the seller, unless the purchaser has stipulated otherwise. “(sahih)
