"The Messenger of Allah ﷺ ruled that the fruit of a palm tree belongs to the one who pollinated it, and that the wealth of a slave belongs to the one who sold him, unless the purchaser stipulated a condition." (Using translation from Ibn Mājah 2213)
إِنَّ مِنْ قَضَاءِ رَسُولِ اللهِ ﷺ أَنَّ ثَمَرَ النَّخْلِ لِمَنْ أَبَّرَهَا إِلَّا أَنْ يَشْتَرِطَ الْمُبْتَاعُ وَأَنَّ مَالَ الْمَمْلُوكِ لِمَنْ بَاعَهُ إِلَّا أَنْ يَشْتَرِطَ الْمُبْتَاعُ
