god has forbidden you to eat that which has not been properly slaughtered blood pork and the flesh of any animal which has not been consecrated with a mention of the name of god. however in an emergency without the intention of transgression or repeating transgression one will not be considered to have committed a sin. god is allforgiving and allmerciful.
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
