We're all aware of the verse (2:219) that says there is both 'benefit' and 'bad' in both consumable intoxicants (the literal word used in the verse is 'wine', I believe) and gambling, but the bad outweighs the benefit:
“There is great detriment in these things as well as some benefits for mankind. But the detriment of them is much greater than the benefit of them. They drag down the individual and collective social potential.” (QXP)
So, the Quran is strongly advising us to never consume (or sell) alcohol, or engage in any form of gambling. I say 'sell' because the verse, when read in full, is clearly discussing economy as well. (And in Yusuf Ali's translation, it says there is 'profit' and 'sin' in wine and gambling, and that the 'sin' outweighs the 'profit'. I'm guessing that the word for 'benefit' in Arabic includes profit? Please correct me if I am wrong.).
