Al-An'aam 6:145

Say [O Prophet], “I do not find in what has been revealed to me anything forbidden to eat except carrion, running blood or the swine flesh – which is impure – or a sinful offering in the name of other than Allah. However, if someone is compelled by necessity – neither driven by desire nor transgressing due limit – then your Lord is All-Forgiving, Most Merciful.”

Say, "I do not find within that which was revealed to me [anything] forbidden to one who would eat it unless it be a dead animal or blood spilled out or the flesh of swine - for indeed, it is impure - or it be [that slaughtered in] disobedience, dedicated to other than Allāh.[357] But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], then indeed, your Lord is Forgiving and Merciful."

[357] Refer to 2:173 and 5:3.

145. Say (O Muhammad صلى الله عليه وسلم): "I find not in that which has been revealed to me anything forbidden to be eaten by one who wishes to eat it, unless it be Maitah (a dead animal) or blood poured forth (by slaughtering or the like), or the flesh of swine (pork); for that surely is impure or impious (unlawful) meat (of an animal) which is slaughtered as a sacrifice for others than Allâh (or has been slaughtered for idols, or on which Allâh’s Name has not been mentioned while slaughtering). But whosoever is forced by necessity without wilful disobedience, nor transgressing due limits; (for him) certainly, your Lord is Oft-Forgiving, Most Merciful."

Say: I find not in that which is revealed unto me aught prohibited to an eater that he eat thereof, except it be carrion, or blood poured forth, or swineflesh - for that verily is foul - or the abomination which was immolated to the name of other than Allah. But whoso is compelled (thereto), neither craving nor transgressing, (for him) lo! thy Lord is Forgiving, Merciful.
