I have a close Muslim personal friend who is getting married soon. Being a close friend, I was invited to his wedding. The wedding takes place in a conventional event venue (i.e., not a mosque or any other religious building). Can I attend his wedding?
Most online responsa, including this one I've seen here, deal primarily with Christian weddings conducted in a church. There are fairly evident halachic issues regarding gatherings of idolaters and entering an idolatrous house of worship. However, those reasons don't apply here. I know that the prevailing view is that Islam is not idolatrous, and one answer to that responsum says that you could attend a Muslim wedding, but does not elaborate. In my mind, this would be even more the case since the venue is not a house of worship, even if it seems like the poskim tend to permit entering a mosque. Would this be the correct view here?
P.S. I know there are tangential halachic issues. For kashrut, I won't be eating anything, and there's no alcohol served. The couple are fairly devout and I must assume that most of the guests would be expected to conform to Islamic dress customs, so I would think that there wouldn't be very many issues of tzniut here either.
