the only things which are made unlawful for you are the flesh of dead animals blood pork and that which is not consecrated with the name of god. but in an emergency without the intention of transgression and rebellion . god is certainly allforgiving and allmerciful.
إنما حرم عليكم الميتة والدم ولحم الخنزير وما أهل لغير الله به فمن اضطر غير باغ ولا عاد فإن الله غفور رحيم
