I have a few muslim friends who swear they've witnessed miracular events, seen/heard the devil, seen ghosts and witnessed the devil disappearing after they recited some Islamic prayer. (I'm completely serious!) When I told one of them I still did not believe in god she took it as a personal offence, in fact, she was completely hysterical about it.
"So you think I'm lying? Do you not believe me?
Now, at risk of offending, I listen politely when people talk about their experiences with god.
Other times when I think I'm safe and talking to a free thinker I let go. Big mistake. I once had a really big argument with this douche at a wedding.
"DON'T MAKE THE QURAN FIT SCIENCE"
"Science is always changing whereas the Quran is constant"
Ergh. Muslims are so touchy with religion.
