Musnad Ahmad 33:925

Muhammad ibn Bakr narrated to us, Ibn Jurayj and Hajjaj informed us, from Ibn Jurayj, 'Ata' informed me that he heard Jabir ibn 'Abdullah saying: We used to not eat from the sacrificial animals (al-budn) except for three days in Mina. Then the Messenger of Allah, may Allah bless him and grant him peace, granted us a concession. He said: "Eat and take provisions." And Hajjaj said: So we ate and we took provisions.
