As per subject I see a lot of Muslims where I live that have Shisha and cigarettes. Isn't this Haram? Aren't cigarettes Haram too or is Shisha considered Hakroon (something like prawns, which is sort of undefined)?
First of all i think you are trying to say MAKROOH by the word Hakroom.
So, there are both opinions that cigarettes are makrooh and haram, but the second opinion that cigarettes are haraam seems more reasonable.
And on the basis of same reasons built for cigarette to be haraam, sheesha is also haraam(or if someone goes with first opinion of makrooh it is makrooh).
If someone is doing something, it doesnot define what his religion's ruling is about that thing.
In the same way as Most of the muslims in the world now a days are connected to banking system which is based on interest (riba) which is haraam in islam, this doesn't mean that interest is halal or permissible in islam.
