Concerning all this over what the Quran says or does not say make your own opinion. So many parts contradict and its now common knowledge from scholars that the book was not written in one go and had parts added and taken away over the centuries. One of the oldest copy's on record has sections that under investigation where covered over in Arabic (over the original written language used i believe was Syriac) with bits added and taken away. Quite a few sections especially those over morality have been shown to have heavily edited, with some part taken and added to make it more or less "strict", with also numerous mistranslations from Syriac to Arabic. Cultural traditions from area's that had only recently accepted the word of Islam have also been shown to have been added to the Quran as time went by. "The Satanic Verses" even support this view that parts of the book where not true and taken out at a later date. This all contradicts the teaching however that the books is divine, no human could have written the book themselves and to question anything in the books itself is wrong.
The problem is that while in Christianity they admit their holy books have been changed over time (albeit scholars in the papal city argue this is due to gods influence himself), even quite liberal Muslims get very offended when the same is suggested to be the same for the Quran. If physical evidence is provided it is still seen with a lot of hostility. Scholars have been stabbed and thrown out of buildings by their own students for suggesting this or showing information that supports this view.
At the end of the day make your own mind up on what you can and "can't" do at uni. In my own opinion you have no way to know what "is" or is not the correct thing to follow. Most Muslims i know find its completely acceptable to go to bars, clubs, pubs etc as longs as you don't drink or "fantasize" about the opposite sex there. And when it comes to dancing I've seen the most devout followers of Islam who have stated to myself dancing to none religious music is wrong only to "head bop" or dance to music when they're out and about especially when they think no one they know is around.
However obviously if you do so take into consideration certain Muslims will not take kindly of you doing so and it can also cause problems such a disputes with family members.
