the Messenger of Allah ﷺ said: "Whoever sells a palm tree that has been pollinated, its fruits belong to the seller, unless the purchaser stipulated a condition. And whoever buys a slave who has wealth, his wealth belongs to the seller, unless the purchaser stipulated a condition."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ بَاعَ نَخْلاً قَدْ أُبِّرَتْ فَثَمَرَتُهَا لِلَّذِي بَاعَهَا إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَمَنِ ابْتَاعَ عَبْدًا وَلَهُ مَالٌ فَمَالُهُ لِلَّذِي بَاعَهُ إِلاَّ أَنْ يَشْتَرِطَ الْمُبْتَاعُ
