Buraida said that the Prophet did not go out on the day of the breaking of the fast till he had some food, but that he did not take any food on the day of sacrifice till he had prayed.
Anas said that when the Prophet came to Medina the people had two days on which they engaged in games. Having asked what their significance was and being told that they had engaged in games on them in the pre-Islamic period, he said, “God has substituted for them something better than them, the day of sacrifice and the day of the breaking of the fast.”
Kathir b. ‘Abdallah on his father’s authority quoted his grandfather as saying that at the two festivals the Prophet said “God is most great” seven times in the first rak'a before reciting from the Qur’an, and five times in the last one before reciting.
