Musnad Ahmad 31:553

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Ayyub, from Abu Qilabah, and from Ibn Sirin, from Abu Sa'id al-Khudri—both of them narrating it from the Prophet, may Allah bless him and grant him peace. One of them said: The Messenger of Allah, may Allah bless him and grant him peace, said: "I had forbidden the meat of the sacrificial animals beyond three days, so eat, take provisions, and store whatever you wish." The other said: "Eat, feed [others], and store whatever you wish."
