Al-An'am 6:145 قل لا اجد في ما اوحي الي محرما على طاعم يطعمه الا ان يكون ميتة او دما مسفوحا او لحم خنزير فانه رجس او فسقا اهل لغير الله به فمن اضطر غير باغ ولا عاد فان ربك غفور رحيم ١٤٥

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."
