Musnad Abu Ya'la al-Mawsili 42:262

Zuhayr narrated to us, Abu 'Amir al-'Aqdi narrated to us, from Zuhayr ibn Muhammad, from Sharik ibn 'Abd Allah ibn Abi Namir, from 'Abd al-Rahman ibn Abi Sa'id, 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."
