Customary practices

Q: Is it permissible for a man to take another wife secretly without knowing of his wife.

Q: In 2-3 months I'm getting married. We are Pakistanis so in our culture before the wedding day we do an event called Dholki where people get together and sing and dance. I'm trying to avoid doing haram things. 

Is it possible to use drums at the event? Is it only duff that is permissible? The event will be a female only event. Can we dance? At the nikaah event can we use music with only vocals and drums? 

Q: The bride chose a musjid which has a ladies section and desires to be present for her nikkah. Is this allowed? 

Furthermore, does she have to choose the musjid closest to home or can she use a musjid 2.5km away?

Q: Is this genuine that for nikaah, first the father and mother of the boy should go and see the bride followed by the sister/sisters and then the boy should go and see the girl for nikaah. This seems as the different rounds of selection.

Q: I am married and a widow who  has children of his own wants to make Nikah with me, but we both want to keep it secret (although in Islam nikah should be notified to family and friends) but in our current circumstances it is very hard. She says that she does not require anything from but to fulfill her sexual desires. We both agree on this that it will remain a secret and will not affect both families at any level. 

As her children are elders and she said that her children will not accept my decision and hate will grow if she declares nikah. So as husband I will fulfill her nan-nafqa although she is repeatedly denying as she is earning so she said she won't require anything. 

The main purpose for this nikah is to avoid sin. So what should we do as a declaration will lead to unpleasant results from both families. 

Please guide in all possible scenerios.

Q: Is it okay to make engagement posters on the engagement of a couple? 

For example: We are pleased to announce the proposal of:

Groom 

Bride 

Please advise.

Q: Is it permissible for children to throw flowers on the bride on the occasion of nikaah? 

Q: Is it permissible for a father to walk his daughter down the aisle on her wedding day?

Q: Is OK for the bride to enter the groom's house for the first time on a Tuesday after nikaah?

Q: My nikaah is to be next week Insha'Allah. I have requested multiple times to not have a function and have it the sunnah way. However my parents are not agreeing and when I try and explain I'm labelled as being disobedient to them, ungrateful and selfish. Both my in laws to be and my parents are saying that you have to compromise for society. This is however not the case, I only wanted to have it in a way that Allah and His Rasul (sallallahu alaihi wasallam) would be pleased.

Out of respect for my in laws and my parents I have now kept quiet. Please advise as to what is the right thing to do.
