I heard the Messenger of Allah ﷺ say, "Whoever buys palm trees after they have been pollinated, their fruit belongs to the seller, unless the buyer stipulates otherwise. And whoever buys a slave who possesses wealth, that wealth belongs to the one who sold him, unless the buyer stipulates otherwise."And from Malik, from Nafi, from Ibn Umar, from Umar, regarding the slave.
أخبرنا عبد الله بن يوسف حدثنا الليث حدثني ابن شهاب
سمعت رسول الله ﷺ يقول من ابتاع نخلا بعد أن تؤبر فثمرتها للبائع إلا أن يشترط المبتاع ومن ابتاع عبدا وله مال فماله للذي باعه إلا أن يشترط المبتاع وعن مالك عن نافع عن ابن عمر عن عمر في العبد
Both of them (Bukhari and Muslim) reported the hadith of Zuhri, from Salim, from his father, from the Prophet, peace and blessings be upon him and his family, "Whoever sells a slave who has wealth."Nafi contradicted him, narrating it from Abdullah bin Umar, from Umar.Nasai said, "Salim is greater in my heart, but the correct view is that of Nafi."
Hafiz said in Fath, vol. 4, p. 402, "There is disagreement regarding Nafi and Salim about the marfu status of everything except the palm-tree story. Zuhri narrated it from Salim from his father as marfu, covering both the story of the palm tree and the story of the slave together. This is how the hadith masters transmitted it from Zuhri. Sufyan bin Husayn differed from them, adding into it a report of Ibn Umar from Umar, marfu, covering all the reports. Nasai narrated it."Hafiz also said, in vol. 5, p. 52, after some discussion, "I say, Tirmidhi transmitted in Jami, on the authority of Bukhari, that he graded both narrations sahih, and he also transmitted from him in Ilal that he preferred the narration of Salim. This has already been explained clearly, in full, in the Book of Sales."Hafiz said in the introduction to Fath, after mentioning Daraqutni's statement and the two hadiths with their two chains, "Bukhari narrated it in both versions, and his purpose in doing so was to use as evidence the story of the pollinated palm tree, which is marfu without any disagreement, as shown by the fact that he included it in the chapters on sharecropping. As for the story of the slave, he narrated it for the purpose of tracing its variant reports, and he made clear the disagreement found within it. So there is no objection to what he did. And Allah knows best." End of quote.
