Nikaah & Marriage Issues

Wali for a revert Muslim

Q: I got a question about marriage. I have recently met a girl that has reverted to Islam, and me and her we want to get married, I am a muslim, my parents approve, but her parents are non-muslim and do not approve her getting married. So I was wondering who will be her Wali, as nobody in her family or house hold are Muslims. How do we do it with witnesses when we are doing nikah and she is 18 so its legal.

Attending a shia marriage

Q: A cousin of mine in a highly deendar environment has married a shia and our family decided not to attend the marriage of our cousin. However, a few of our deendar relative and elders called us and scolded us for doing Qata' Rahmi. Q.1 What is the fatwa on attending a marriage/nikah being arranged by Shia? Is it permissible or impermissible? Q.2 Is it Qata' Rahmi on our part to boycott the marriage?

Zina before nikaah

Q: When I met my wife and asked her hand in marriage, she agreed but we committed zina before she introduced me to her parents and before we were joined together. She was pregnant when we were joined together. What is the status of our marriage and the first child? When is marriage said to have taken place in Islam or when are the two lawful to have sex?
