It was narrated from Abdur-Rahman bin Abis that his father said: "I came in to Aishah (RA) and said: Did the Messenger of Allah ﷺ forbid (eating) the meat of sacrificial animals after three day? She said: Yes Hardship had befallen the people, and the Messenger of Allah ﷺ wanted the rich to feed the poor. Then she said: I remember the family of Muhammad eating the trotters after fifteen days. I said: Why is that" She laughed and said: The family of Muhammad never ate their fill of bread and something to go with it, for three days in row, until he met Allah, the Mighty and Sublime," (Sahih)
