Musnad Abu Ya'la al-Mawsili 115:78

Abu Bakr narrated to us, Waki' narrated to us, from Shu'bah, from Qatadah, from Anas, that the Prophet (peace and blessings of Allah be upon him) saw some meat and said, "What is this?" They said, "It was given as charity to Barirah." He said, "It is charity for her, and it is a gift for us."
