http://www.youtube.com/watch?v=vmLDRHlOo0U Not only drinking but attending such parties where wine is being servered is HARAM....refer to this Q&A http://www.islamqa.com/en/ref/45789 Ibn Qudaamah (may Allaah have mercy on him) said in al-Mughni (7/214): If a person is invited to a wedding feast in which evil things will take place, such as wine, musical instruments, etc, and he is able to attend and remove those evils, then he must attend and denounce them, because then he will be fulfilling two duties: accepting the invitation of his Muslim brother and removing evil. But if he is not able to denounce them then he should not attend. If he does not know about the evils until he gets there, he should remove them. If he cannot, then he should go away. Something similar was stated by al-Shaafa'i. 2- Chapter: 5 , Verse: 90 Believers, wine and gambling, idols and divining arrows are abominations from the work of satan. Avoid them, in order that you prosper. 3- Chapter: 5 , Verse: 91 satan seeks to stir up enmity and hatred among you by means of wine and gambling, and to bar you from the remembrance of Allah and from praying. Will you not abstain from them? share with your family and friends.
