he has only forbidden you dead meat and blood and the flesh of swine and any over which the name of other than allah has been invoked. but if one is forced by necessity without wilful disobedience nor transgressing due limits then allah is oftforgiving most merciful.
إنما حرم عليكم الميتة والدم ولحم الخنزير وما أهل لغير الله به فمن اضطر غير باغ ولا عاد فإن الله غفور رحيم
