Musnad Ahmad 25:33

He said: Isma'il narrated to us, Ayyub narrated to us, he said: I do not know if I heard it from Sa'id ibn Jubayr or if I was informed of it from him, he said: I came to Ibn Abbas at Arafah while he was eating a pomegranate. He said: "The Messenger of Allah, peace and blessings of Allah be upon him, broke his fast at Arafah, and Umm al-Fadl sent milk to him, so he drank it." And he said: "May Allah curse so-and-so; they intended toward the greatest of the days of Hajj, and they erased its adornment, and the adornment of Hajj is only the Talbiyah."
