Masaail pertaining to the Wali and Compatibility between spouses

Q: Can a Muslim girl marry a Muslim boy without her parents consent? They like each otherand both of them study in a well-known varsity. Both of them are aware of their future but their parents will not allow them to marry now because both of them are not established. Recently they got involved in some sort of physical relationship that they cannot resist. So they want to be married to get rid of the sin. Can they marry now if they want to without their parents consent?

Q: If a girl acts as the wakeel in a marriage, is the marriage valid?

Q: Can a step grandfather, without the permission of the biological father give my daughters hand for nikaah. Her biological father says that he has to give permission for the step grandfather to stand as her guardian or her nikaah is invalidated.

Q:

1. Can a Muslim lady who is a widow and has a child from her first husband, enter into nikaah with a Muslim man without seeking permission from her father?

Q: If an Aalimah who wears full niqab and does not intermingle with men or watch tv movies etc. gets a proposal from a doctor whos a hafiz, which means he probably does khalwat with women and he watches football, would you even tell the Aalimah to consider him? He is praised for his akhlaaq. He also visits a female dentist.

Should the Aalimah even consider him. She has hope of doing amr bil maroof but fears marriage problems thereafter. Her grandfather (Allah enlighten his qabr) was a Shaikhul Hadeeth.

Q: I want to ask about the quality of knowing a religion oriented person prior to selecting a spouse on religion features.

Q: I am 23 yrs old female. I have recently met a guy through a mutual friend who is 7 yrs elder to me. We have met only once and he told me he has a liking towards me and would like to talk to my parents regarding marriage. We know each other since 3 months and I find him perfect. Off lately,he told me that he is a sunni and he would want me to be a sunni Muslim and indulge in all the activities like niyaz and fatihah since it's the family tradition. I am very confused regarding this.

Q: I am in a love with a girl for the last 7 years. I asked my mother to go there and ask for rishta. We all went to her home and gave our proposal. They said they shall let us know a week later. After a week they invited us to their home and said we are fine and said Yes for marriage. Before going there me and my mother perform Istikhara and it was good but after saying yes they perform istikhara but saw negative signs. I asked a Mufti and he said you cannot perform istikhara after saying Yes. Please tell me what should I do?
