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, “I do not find, in what has been revealed to me, anything (out of the cattle under discussion) prohibited for anyone who eats it, unless it be carrion or blood that pours forth, or flesh of swine - because it is impure - or there be an animal slaughtered sinfully by invoking on it the name of someone other than Allah. However, if anyone is compelled by necessity, neither seeking pleasure nor crossing the limit, then your Lord is Most-Forgiving, Very-Merciful.”
