he has only forbidden dead flesh blood the flesh of swine and any animal which is slaughtered as a sacrifice for other than allah. but if one is forced by necessity without willful disobedience nor transgressing then allah is pardoning most merciful.
إنما حرم عليكم الميتة والدم ولحم الخنزير وما أهل لغير الله به فمن اضطر غير باغ ولا عاد فإن الله غفور رحيم
