Musnad Abu Ya'la al-Mawsili 115:237

Muhammad ibn Yahya ibn Abi Samina al-Shami 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, entered the house of ‘Aishah and saw some meat. He said, "Roast some of it for us." They said, "O Messenger of Allah, it is charity (sadaqah)." The Messenger of Allah, peace and blessings of Allah be upon him, said, "Roast some of it for us, for it has reached its place."
