Sa'id b. al-‘As said he asked Abu Musa and Hudhaifa how God’s Messenger said “God is most great” on the day of sacrifice and of the breaking of the fast. Abu Musa said he uttered it four times as he did at funerals and Hudhaifa said that that was correct.
Ja'far b. Muhammad told in mursal form that the Prophet, Abu Bakr and ‘Umar said “God is most great” at the two festivals and when praying for rain seven times in the first rak'a and five times in the second. They prayed before the sermon, and recited the Qur’an in a loud voice.
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.
