"Zaid bin Arqam came and Ibn Abbas said to him, reminding him: "What did you tell me about the game meat that was given to the Messenger of Allah when he was in Ihram?" He said: "Yes, a man gave him a piece of game meat but he returned it and said: 'We cannot eat it, we are in Ihram.'"
Sunan an-Nasa'i Book 24, Hadith 204
