Holy Quran » AN NAHL : 115

He has only forbidden to you dead animals, blood, the flesh of swine, and that which has been dedicated to other than Allah . But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit] - then indeed, Allah is Forgiving and Merciful.

{ إنما حرم عليكم الميتة والدم ولحم الخنزير وما أهل لغير الله به فمن اضطر غير باغ ولا عاد فإن الله غفور رحيم } .
