Masaail pertaining to the Wali and Compatibility between spouses

Q: Girl's choice in marriage is final though violating other family and status equality as given in fiqh of marriage. Allah orders children not to cause grievous hurt to the heart of parents. Allah says, he does not delay punishment to such children in this very world. So how can such marriages be happy? Is not the marriage with the approval of both the girl and her parents more meritorious and rewarding? And are parents entitled to say to the girl that if she's bent upon her own choice, she should do it without parents taking any part in it as they aren't accepting her choice?

Q: Due to certain circumstances my daughter and I have had little contact. In December she told me she want to get married and that she would like if I will be her wakheel to give her off on her wedding day. They were going to come see me to finalise everything. I was not contacted again till a few days before the wedding by her mother asking if I was still going to give her off. I responded by saying nobody asked me for her to get married. The mother answered that I never had time for the daughter and that I don't have any rights over the daughter. I then said that she must then go to her Imaam and make him her wakheel. They then got married. Is this the correct way? Is her marriage halaal?

Q: A friend states the following problem he is in. He has been in contact with a girl for just under two years. The girls parents agree for them to make nikaah but the girl's granny (daadi) refuses for it to happen since the boy is not Gujraati speaking, he is from an Urdu background. The granny has brought numerous guys to view the girl despite her not agreeing. So the father of the girl is trapped between his daughter and his mother. She also says that it is not jaaiz for the two since he is from a lower cast and what will her family say to them. My friend wants to make nikaah with the girl and she is afraid of marrying another person since she has opened up herself to him and he is the only guy she has been in contact with. So she cannot get into nikaah with someone else because she will fall into haraam with this guy again. Please advise should the guy's family approach the girl's family for a nikaah?
