( Muhammad ) , tell them , " I do not find anything which has been made unlawful to eat in what has been revealed to me except carrion , blood flowing from the body , pork [ for pork is absolutely filthy ] and the flesh of the animals slaughtered without the mention of the name of God . However , in an emergency , when one does not have any intention of rebelling or transgressing against the law , your Lord will be All-forgiving and All-merciful .
