"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) (Using translation from Nasāʾī 4636)
عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ بَاعَ عَبْدًا فَمَالُهُ لِلْبَائِعِ إِلَّا أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَمَنْ بَاعَ نَخْلًا فِيهَا ثَمَرَةٌ قَدْ أُبِّرَتْ فَثَمَرَتُهَا لِلْبَائِعِ إِلَّا أَنْ يَشْتَرِطَ الْمُبْتَاعُ» وَقَالَ أَبُو عَبْدِ الرَّحْمَنِ مَطَرُ بْنُ طَهْمَانَ ضَعِيفٌ
