Musnad Ahmad 1225:1

'Abd al-Malik ibn 'Amr and 'Abd al-Rahman ibn Mahdi narrated to us, they said: Zuhayr—meaning Ibn Muhammad—narrated to us, from Sharik ibn 'Abd Allah, from 'Abd al-Rahman ibn Abi Sa'id al-Khudri, from his father and his uncle Qatadah, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Eat the meat of the sacrificial animals and store it."
