he has forbidden you only the maitah and blood and the flesh of swine and that which is slaughtered as a sacrifice for other than allah. but if one is forced by necessity without willful disobedience nor transgressing due limits then there is no sin on him. truly allah is oftforgiving most merciful.
إنما حرم عليكم الميتة والدم ولحم الخنزير وما أهل به لغير الله فمن اضطر غير باغ ولا عاد فلا إثم عليه إن الله غفور رحيم
