Hadith.2733 - Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked about a person in the state of ihram who hunts game and pays its expiation: Should they eat it or discard it?
Imam عليه السلام said: "If they eat it, then another expiation becomes obligatory upon them."
They asked: "What should they do with it then?"
Imam عليه السلام replied: "They should bury it."
For anyone upon whom expiation is obligatory for something they did while in the state of ihram:
If they are performing Hajj, they must slaughter their offering in Mina.
If they are performing Umrah, they must slaughter it in Mecca near the Kaaba.
If a person in the state of ihram is compelled to choose between eating hunted game or carrion, they should eat the game and pay the expiation. If they eat the carrion, there is no harm upon them.
