Abu Saeed bin Malik al-Khudri returned from a journey, and his family brought him some of the meat from the sacrificial animals. He said, "I will not eat it until I ask about it."So he went to his maternal brother Qatada bin Numan, who had been a participant at Badr, and asked him about it.Qatada replied, "Something happened after you left that overturned the previous prohibition against eating the meat of sacrifices beyond three days."
أن أبا سعيد بن مالك الخدري قدم من سفر، فقدم إليه أهله من لحوم الضحايا، فقال: ما أنا بأكله حتى أسأل، فانطلق إلى أخيه لأمه- وكان بدريا- قتادة بن النعمان، فسأله فقال: إنه حدث بعدك أمر نقض لما كانوا ينهون عنه من أكل لحوم الأضحى بعد ثلاثة أيام.
Bukhari narrated it in the Book of Military Expeditions (3997) from Abdullah bin Yusuf, from Layth, who said, Yahya bin Saeed narrated to me, from Qasim bin Muhammad, from Ibn Khabab (whose name was Abdullah), and he related it. He also narrated it in the Book of Sacrifices (5568) through another route from Yahya bin Saeed with similar wording.A note of caution, the hadith was also narrated through another route from Abu Saeed, but with a reversal in the text. This is what Nasai (4428) and Imam Ahmad (11176) narrated, and Ibn Hibban (5926) graded it sahih, all of them through Yahya bin Saeed (that is, Qattan), from Saad bin Ishaq, who said, Zaynab narrated to me, from Abu Saeed Khudri, that the Messenger of Allah ﷺ forbade eating the meat of sacrificial animals beyond three days. Then Qatada bin Numan, who was Abu Saeed's maternal brother and had been present at Badr, came to visit, and they served food to him. He said, "Did the Messenger of Allah ﷺ not forbid this?" Abu Saeed said, "Something new happened regarding it. The Messenger of Allah ﷺ forbade us from eating it beyond three days, but then he gave us permission to eat it and store it."Its narrators are trustworthy except for Zaynab, who was the daughter of Kaab bin Ujra and the wife of Abu Saeed Khudri. She is deemed "acceptable" as stated in Taqrib, meaning when her narration is corroborated. Her account of the basic story has indeed been corroborated, but a reversal occurred in her wording, where she made Abu Saeed the narrator of the hadith and Qatada bin Numan the one who abstained from eating, which contradicts what is found in the Sahih. This may be attributable to Zaynab bint Kaab.I say, what supports the version in the Sahih is the following narration.
