Masaail pertaining to the Wali and Compatibility between spouses

Taking a second wife

Q: I am a married man. I was in love with a Hindu girl even before my wedding. Now I feel that I need to seperate from my wife and marry the Hindu girl. My wife is ready for a second marriage but the Hindu girl does not want to accept it. She will be a Muslim after the wedding. I dont have much feeling left for my wife and my life is really a problem without the other girl. What should I do? 

Marrying a girl without her father's permission

Q: I used to talk to a girl from my relatives. We decided to get married. At that time the girl lived at her grandfather’s house. I went there several times. The grandfather and the girl told me that the girl’s father gave the girl’s grandfather permission for her to get married. In 2017 nikaah was performed. Mehr was decided, witness were present, ijaab and qabool took place and the khutbah of nikaah was performed. The girls parents did not know about the nikaah.

Once nikaah was done, we meet twice and we were alone in the house. Now I want to complete the rukshati. I want to know if this nikaah is valid or not? 

Compatibility between spouses in a secret nikaah

Q: One of my friend proposed me 2 years back. I liked him from the beginning but I had a firm mindset that if my parents agree then we'll get married otherwise not. During the summer holidays I went back home and told my parents about him and they both said no. I thought that if they meet him once, they might change their mind. I told my brothers about him, they met him and they both said that he is a pious person with good character but if dad has said no then its a NO. Then I told my friend that my parents refused.

We had a few fights but we again became friends. 2 months back I started spending more time with him as I lost almost all my other friends but we always tried our best to maintain a halal distance. He started mentioning about the secret nikah here and there. Everytime he did, I got annoyed at him and told him not to think about it.

One day he said that either we do nikah or our friendship will be over forever. I said that if you want to finish the freindship then go ahead... bear in mind that at that time I was going through a tough time and depression and loneiness.

After a couple of days I went to him and said to him that I'm ready for the nikah. We did nikah in the presence of 2 witnesses who were both Muslim and mature.

My question is, according to the Hanafi fatwa "a mature girl can give herself in marriage without walis consent in the presence of 2 witnesses but the both boy and girl should be of same "social status".

That boy is African and I'm Pakistani. Do you think that the 2nd part of the fatwa in anyway nullifies the nikah or makes it invalid?

Secret nikaah

Q: I am 32 years old. I am married with 2 kids. I want to marry a girl who is 17 years old but she is young so she can't tell her parents. To avoid sin we have accepted each other in front of two Muslims that we are husband and wife. I asked her "do you accept me as your husband" and she said "yes". Are we husband and wife now?
