Knowingly Committing Haram
That is ok.but.For example:alcohol even a drop is haram.There is a opinion in hanafi where a little alcohol is halal(not sure which extent).If a person drinks little alcohol considering it halal would he be sinful (i am not saying if he repents later or not etc). Similarly if a person knows (according to hanafi school of thought) that all seafood except fishes is haraam.If he eat some seafood except fishes (having in mind it is haraam, intentionally),would he be sinful (because except hanafi all says that all seafood is halal)?in short if a person eats something intentionally considering it haraam(which is actually not haram),would he be sinful?
