Masaail pertaining to the Wali and Compatibility between spouses

Q: When the Imam leads the nikaah, does he have to ask the girl with two witnesses or just two witness is enough. In our locality people say Imam should ask the girl and they get offended if the Imam doesn't go.

Q: I made nikah with my husband. He is a Maliki . I do not folow any madhab. The imam who made a nikah implemented it without a wali according to the hanafi madhab. After I found out that there are sahih hadiths proving that there is no nikah without a wali. Also most of the madhabs don't accept the nikah without a wali. Please help me to clear the situation, should we make a new nikah or this one is valid?

Q: Can I marry someone my mother don't approve of because the man was previously married? Is it wrong to still marry him?

Q: I like this boy and he likes me.We are ready to get married however my parents disapprove because we are of different casts. I do not want to go
against my parents but are they allowed to do this according to Islam? They have not met him  or his family. What is the best way to deal with the
situation and what can I read?

Q: I have found a spouse for myself and a very good one alhamdulillah, however he is from a different culture from me. I have nothing against interracial marriage or different cultures getting married in fact I find it very fascinating. I am scared what my family might say and that they will not accept. My brother is also a mufti and there are people in my area who have married from different cultures but my parents may have a different opinion when it comes to there own family. What should I do to overcome being scared and to be confident to tell my family?

Q: Can I marry without the concent of my parents and will it harm me in the future and hereafter?

Q: I have a "Memon" friend who wants to marry a "Surti" girl. His parents do not wish this to happen. I obviously know that the parents are in the wrong to draw a divide in this manner as they are both Muslim. However, I am also aware that the blessings of the parents are important to a marriage, and going against them will most probably result in a severing of family ties. Firstly, should I try to speak to the parents and/or mediate between the parties. And secondly if this fails do I still encourage the marriage or do I encourage him to respect his parents' wishes. Please advise

Q: A couple made zina (shaf'ee) and now they want to get married. Do they need permission from the awliyaa? 

Q: I have got to know a boy from my town and we both have fallen for each other. I performed salaahtul istikhara and my dreams where positive. However his parents do not approve of me. I have been modern but I try hard to live my life Islamically. He has performed istikhara salaah as well but didn't have any dreams. We really want to make our relationship halaal. What should we do?

Q: I am 30 years of age and divorced with 2 kids a girl and a boy. I have been a lone parent for over 8 years now and I really feel that I need a partner and at the same time I worry for my kids too. My parents don't want to get me remarried because of the children. My mum worries too much about the kids that if their own father left them then how can a step father take care of them. I agree with her too but I am there for my children and always will be, they are my life, but there are some good people out there too. A father can leave his kids but a mother can never leave her children. Could you please tell me a dua or a wazifa that I can read so that my parents think about me and my children, accept that fact and I get a very good life partner that will accept me with my 2 kids and fulfil the duties of a real father.
