Musnad Ahmad 32:231

Isma'il narrated to us, Ayyub narrated to us, from Muhammad, from Anas, who said: The Messenger of Allah (ﷺ) said on the Day of Sacrifice: "Whoever slaughtered before the prayer, let him repeat it." A man stood up and said: "O Messenger of Allah, this is a day in which meat is desired." And he mentioned a matter concerning his neighbors, as if the Messenger of Allah (ﷺ) believed him. He said: "And I have a young goat that is dearer to me than two meat-sheep." He said: So he granted him a concession, and I do not know if his concession reached anyone else or not. He said: Then the Messenger of Allah (ﷺ) turned toward two rams and slaughtered them. The people then went toward the spoils (of the sheep) and distributed them, or he said: they divided them.
