إِنَّمَا حَرَّمَ عَلَيْكُمُ الْمَيْتَةَ وَالدَّمَ وَلَحْمَ الْخِنزِيرِ وَمَا أُهِلَّ بِهِ لِغَيْرِ اللَّهِ ۖ فَمَنِ اضْطُرَّ غَيْرَ بَاغٍ وَلَا عَادٍ فَلَا إِثْمَ عَلَيْهِ ۚ إِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ (173)
(2:173) Allah has only forbidden you to eat what dies of itself, and blood and swine flesh and what has been consecrated to any other name than of Allah. *171 But one will incur no sin if, forced by absolute necessity, he eats of any of these forbidden things, provided he has no intention of transgressing the law and does not take more than what is absolutely indispensable: for Allah is very Forgiving and very Merciful. *172
*171). This applies to the flesh of an animal slaughtered in the name of anything and anyone other than God as well as to the food prepared as an offering to someone other than God. God alone is the master of everything - of the animal whose flesh we consume as well as of every other kind of food - and it is He Who has mercifully provided us with them. Hence, if it is appropriate to pronounce any name as an expression of gratitude, of consecration, it can only be the name of God. To use anyone else's name means that we believe that there is some other being either instead of or in addition to God which deserves to be acknowledged as our Lord and Benefactor.
*172). This verse grants permission to use prohibited things with three stipulations. First, one must be in a state of extreme compulsion, for example, being gravely ill or being so hungry and thirsty that one's very life is in danger, and a prohibited thing is all that is available to save one's life. Second, the person concerned should have no inclination to violate the Law of God. Third, in consuming the prohibited thing one should not exceed the limits of bare necessity. If a few bites or a few drops are enough to save one's life, one ought not to go beyond the absolute minimum.
