Only four foods are banned in the Qur'an. Pig, the flesh of dead animals (like previously dead, obviously all animals are dead when we eat them), blood, and those killed in the name of other than Allah. It says in the Qur'an not to pray intoxicated and that Alcohol is a tool of the devil. More of a warning against Alcohol then an outright ban. Many wahhabi's ban alcohol, they also ban music because it says in the Qur'an to avoid "idle talk" so this somehow also includes banning all music.
I've read reports that enjoying a cold beer in Iran might draw punishments with it in the proportions of how Americans lock up Terrorists.
I did a lot of tutoring when I was younger and most of the kids at the place were Turkish(around 60%). So since I was one of the younger tutors, they wanted to talk to me about anything and would listen to anything I talk about with my colleagues.
And when we were talking about activities that involve alcohol kids were usually leaving to listen. When asking them why, they'd all tell me that the Qur'an despises intoxication. I know they were active Muslims, but since they were young I didn't know how trustworthy their displays were, since they were younger and maybe their parents used that as a trick to tell them to stay away from activities that involve drinking.
That's why I wanted to ask.
