[Machine] Narrated by Prophet Muhammad ﷺ , "Whichever man sells a palm tree that has been pollinated and its fruits have appeared, the first harvest will belong to its Lord (i.e., the palm tree will belong to the buyer for the subsequent harvests) unless the buyer specifies otherwise." Umar ibn Al-Khattab also ruled, "Whichever man sells a slave who owns wealth, his wealth will belong to his Lord (i.e., the slave's wealth will transfer to the buyer) unless the buyer specifies otherwise." This was also narrated by Salim ibn Abdullah from his father from Prophet Muhammad ﷺ regarding palm trees and slaves, and this is mentioned at its proper place, InshaAllah (if Allah wills).
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ أَيُّمَا رَجُلٍ بَاعَ نَخْلًا قَدْ أُبِّرَتْ فَثَمَرَتُهَا لِرَبِّهَا الْأَوَّلِ إِلَّا أَنْ يَشْتَرِطَ الْمُبْتَاعُ قَالَ وَقَضَى عُمَرُ بْنُ الْخَطَّابِ ؓ أَيُّمَا رَجُلٍ بَاعَ مَمْلُوكًا لَهُ مَالٌ فَمَالُهُ لِرَبِّهِ الْأَوَّلِ إِلَّا أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَرَوَاهُ سَالِمُ بْنُ عَبْدِ اللهِ عَنْ أَبِيهِ عَنِ النَّبِيِّ ﷺ فِي النَّخْلِ وَالْعَبْدِ جَمِيعًا وَذَلِكَ يَرِدُ فِي مَوْضِعِهِ إِنْ شَاءَ اللهُ تَعَالَى
