Al-Muwatta Hadith 20.86

Yahya related to me from Malik, from Hisham ibn Urwa, from his father, that A'isha, umm al-muminin, said to him, "Son of my sister, it is only for ten nights, so if you get an urge to do something, leave it," by which she meant eating game-meat. Malik said that if game was hunted forthe sake of a man who is in ihram and it was prepared for him and he ate some of it knowing that it had been hunted for his sake, then he had to pay a forfeit for all of the game that had been hunted on his behalf. Malik was asked about whether someone who was forced to eat carrion while he was in ihram should hunt game and then eat that rather than the carrion, and he said, "It is better for him to eat the carrion, because Allah, the Blessed and Exalted, has not given permission for someone in ihram to either eat game or take it in any situation, but He has made allowances for eating carrion when absolutely necessary." Malik said, "It is not halal for anyone, whether in ihram or not, to eat game which has been killed or sacrificed by some one in ihram, because, whether it was killed deliberately or by mistake, it was not done in a halal manner, and so eating it is not halal. I have heard this from more than one person. Somebody who kills game and then eats it only has to make a single kaffara, which is the same as for somebody who kills game but does not eat any of it."
