Re: halal wedding entertainment
I don't see anything wrong with music (especially on wedding). Again, don't wanna get into the issue of haram and halal but would like to talkl about just one hadith here. There was a wedding in ansar. Aisha (R.A) attended the wedding. When she came back, Prophet (S.A.W) asked her how the wedding was. She said 'It went fine Alhamdulillah'....The Prophet (S.A.W) asked 'Was there any kinda music @ the wedding?'........She said 'No'........He said 'It wud've been better if music was arranged as the Ansar are fond of music'.........And this hadith can be found in bukhari and other books.
Have music for your guests so they are not bored. Have separate area for women and seperate area for men. Don't spend too much money on useless things.
