Husayn (may Allah have mercy on him) says that Mujahid (may Allah have mercy on him) was asked: Should a man eat from his sacrifice? He said: There is no harm to him if he does not eat from his sacrifice. The saying of Allah Almighty: "So eat of them" [Surah al-Hajj: 28] is like His saying: "And when you have left the state of ihram, then hunt" [Surah al-Ma'idah: 2]; so whoever wishes may hunt.
