The Pork Forbiddance
The prohibition of pork is mentioned in the Holy Qur'an in at least four places:
"He hath only forbidden you dead meat, and blood, and the flesh of swine, and that on which any other name hath been invoked besides that of Allah. But if one is forced by necessity, without wilful disobedience, nor transgressing due limits - then is he guiltless. For Allah is Oft-Forgiving Most Merciful." (The Cow's Chapter ...verse no: 173)
"Forbidden to you (your food) are: dead meat, blood, the flesh of swine, and that on wish hath been invoked the name of other than Allah; that which hath been killed by strangling, or by a violent blow, or by a headlong fall, or by being gored to death; than which hath been (partly) eaten by a wild animal; unless ye are able to slaughter it (in due form); that which is sacrificed on stone (altars); (forbidden) also is the division (of meat) by raffling with arrows: that is impiety. This day have those who reject Faith given up all hope of your religion: yet fear them not but fear me. This day have I perfected your religion for you, completed my favour upon you, and have chosen for you Islam as your religion. But if any is forced by hunger, with no inclination transgression, Allah is indeed Oft-Forgiving, Most Merciful." (The table's Chapter...verse no: 3)
"Say: I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it, unless it be dead meat, or blood poured forth, or the flesh of swine, for it is an abomination or, what is impious, (meat) on which a name has been invoked, other than Allah's. But (even so), if a person is forced by necessity, without wilful disobedience, nor transgressing due limits, thy Lord is Oft-Forgiving, Most Merciful." (The Cattle's Chapter...verse no: 145).)
"He has only forbidden you dead meat, and blood, and the flesh of swine, and any (food) over which the name of other than Allah has been invoked. But if one is forced by necessity, without wilful disobedience, nor transgressing due limits, then Allah is Oft-Forgiving, Most Merciful." (The Bee's Chapter...verse no: 115)


pork and Qu'ran
I'm curious, just what constitutes "forced by necessity, without wilful disobedience..."?
At what point can a person legitimately be forgiven for eating pork and at what point is it just being lax?
