The forbidden meat (supermarket meat is not permissible because it is not slaughtered in the Name of the Creator)5:3-4
5:3 You are forbidden (to consume) the dead, blood and the flesh of swine; also flesh dedicated to any other than Allah, the flesh of strangled (animals) and of those beaten, that which is killed by falling, gored to death, mangled by beasts of prey, unless you find it (still alive) and slaughter it; also of animals sacrificed on stones (to idols). (You are forbidden) to seek division by the arrows, that is debauchery. Those who disbelieve have this day despaired of your religion. Do not fear them, but fear Me. This day I have perfected your religion for you and completed My favor to you. I have approved Islam to be your religion. (As for) he who does not intend to commit a sin but is constrained by hunger to eat of what is forbidden, then surely Allah is Forgiving, Merciful.
5:4 They ask you what is lawful to them. Say, 'The good things are lawful to you, as well as that which you have taught the birds and beasts of prey to catch, teaching them of what Allah has taught you. Eat of what they catch for you, pronouncing upon it the Name of Allah. And fear Allah, Allah is Swift at reckoning.'
