He has forbidden you only carrion (any animal that dies by itself), and blood, and swine flesh, and anything --- (not just meat) --- that has been dedicated to any other than Allah (be it any person, an ancestor, a saint, an idol or a tomb (5:3)). But, he who is compelled out of necessity, neither craving nor indulging in excess, it is not a dragging violation for him. Behold, Allah is Forgiving, Merciful.
