I asked Ayesha, "Did the Prophet ﷺ forbid eating the meat of sacrificial animals after three days?"She replied, "He only did that in a year when people were suffering from hunger, for he wanted those with means to feed the poor. We ourselves used to keep a sheep's shank for as long as fifteen days."Someone asked, "What forced you to do that?"She laughed and said, "The family of Muhammad ﷺ never ate their fill of seasoned wheat bread for three days in a row until he passed on to meet Allah."
قلت لعائشة: أنهى النبي ﷺ أن تؤكل لحوم الأضاحي فوق ثلاث؟ قالت: ما فعله إلا في عام جاع الناس فيه، فأراد أن يطعم الغني الفقير، وإن كنا لنرفع الكراع بعد خمس عشرة! قيل: ما اضطركم إليه؟ فضحكت قالت: ما شبع آل محمد ﷺ من خبز بر مأدوم ثلاثة أيام حتى لحق بالله.
Bukhari narrated it in the Book of Foods (5423), and Muslim in the Book of Asceticism and Softening of Hearts (23:2970), via Sufyan (that is, Thawri), from Abdul-Rahman bin Abis, from his father (that is, Abis bin Rabia Nakhai Kufi), and so on as mentioned. The wording given is Bukhari's, while Muslim limited himself to her saying, "The family of Muhammad ﷺ never had their fill..." and so on.
