Masaail pertaining to the Wali and Compatibility between spouses

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?

Q: I have a sister and she is 25 years old and I am her elder brother. Recently we have fixed my sisters marriage with a person who I know. Now I came to know she loves another man, so personally me, my brother, my mother and father tried to contact the boy who my sister loves. When we asked him he says that he don’t want to marry my sister. I did my utmost level to make my sister marry the person she loves but he don’t want to marry her at any cost and he keeps giving excuses of his parents.

Now my sisters marriage is already fix and my sister says that whatever my parents say she will do. I am concerned about my sister and I want to see her happy.

A few days back I spoke to her and explained to her, so she said she will marry with the person her parents wants. Somtimes she is happy somtimes she is sad. I don’t knw what to do. Will I be accountable infront of Allah if she married to the person of our choice.

Q: Can a Asian man marry a Muslim woman that isnt Asian by race?

Q: During my nikah, one of the witnesses asked me who I wish to take as my representative, and I said my brother. My question is:

1. Is it necessary for the bride to verbally appoint her representative or can her brother, being her wali, act on her behalf without her saying so.

2. If I didnt say my brothers full name does this affect the validity of the nikah. On the marriage certificate my brothers full name is written.

3. If nothing of the dowry amount is paid immediately does this have affect the validity of the nikah?

Q: What matters are considered in Kafaa'at and if kafaa'at is​ not found what is the status of the nikaah which was done without the consent of the wali?

Q: Is the Nikaah done without the permission of a Wali, will it be valid?

Q: If the parents have done everything they could for their children, for example, my father has scarficed a lot for his children, he gave us education. We are 6 sisters and 3 brothes. All my brothers Alhamdulillah are engineers and two elder sisters are married and two are Alhamdulillah doctors.

My question is that one of my sisters, who is a doctor is being forced to marry our cousin who is my father's nephew. Years ago the relation was tied and my sister had no clue about it, she got to know later when it was made official. After her graduation my parents, even my brothers and two elder sisters who are married are forcing her to marry the cousin. All these years she was highly depressed over it and would cry in sajood. Meanwhile our parents and our elder siblings have told us that we should marry whoever our parents want us to because they've sacrificed a lot for us and that our father gave us education in the society where girls aren't supposed to get out and study. And in our society we do not marry out of the cast. So we have no option. We have to marry our cousins. It doesn't matter if they're educated or not.

Basically my question is that are we disobeying our parents or taking their sacrifices as for granted if we aren't willing to marry who they want us to get marry? My sister is really depressed. All these years she'd cry but now when the days have come close she has agreed to marry because she has been pressurised if she doesn't get married to whoever her father wants, it'd hurt her parent's feelings plus she has no choice rather than the cousin cause her age will pass by and none will marry her because as I mentioned above we are not supposed to get married out of our cast according to our society.

Q: I am a Muslim Arab born and live in the U.K. I'm in the process of marrying an amazing Bengali girl. There's just one problem, her father and mother were divorced ages ago and she hasn't seen her father in 4 years. She has tried to contact him to be her wali as that's what the Quran says but no reply. It's been about a week and half but we want the nikah to be as quick as possible so we don't delay it. What should we do? Should we wait till her father replys no matter how long we wait? Her father has no family here in the U.K. either?

Q: Please advise: I am a 25 year old female and feel that I am ready for marriage. My parents have been looking for a suitable spouse for me. So far I have had boys (who were suggested my family members/family friends) come home to propose but it did not go further because both I and my family felt that the boy and I were not compatible. An old friend (female) recently contacted me through Facebook and said that her cousin (who went to the same school as me -7 years ago) is ready for marriage and would like to contact my parents. I am aware of the fitna of social media and have been very careful about how I use it. I do not post any pictures of myself so I am certain that this is not the reason that her cousin would like to speak to my parents. Would you advise that I give this friend my parents' contact details? Or would it be better to turn down her request and wait for another proposal to be suggested by a family member?
