Conditions for the validity of Nikaah

Q: I have an important question which I would like to ask on behalf of a friend of mine. I shall explain the whole situation and would like some Islamic advice on the matter.

Basically one my friends family have taken him to Pakistan to get married to one of his relatives there, at the time of his travel he was unaware of this. My friend likes somebody else who he would like to marry but due to his family pressure and everything he has unwillingly got engaged to his relative from Pakistan although his heart is still with the girl in UK whom he loves and wanted to wife. The girl and him have mutual feelings and still want to be together, he is not willing to forget this girl and claims he still wants to be with her, but his family have trapped him into this wedding which he is not happy with. I would just like to know on his behalf whether this marriage which was forced upon him is considered valid in Islam, because a few islamic websites I have checked on have said a marriage which is forced or not the happiness of an individual it is not valid in Islam's and Allah's eyes, is this true?

Also would it be appropriate for my friend and the girl he loves to still stay in contact regardless of this marriage which has been conducted without his happiness? What would be the best Islamic way to tackle such a situation?

Q: Recently, I have chosen a bride for marriage. The bride told me that she had a boyfriend and her boyfriend did sex with her two times by explaining that since they both agreed to marry each other, so, they are husband and wife. The girl did not know the exact hadith and rules. She believed the boy and agreed to have sex with him. After that the girl consulted a mufti and she was informed that it was an invalid marriage. The girl stopped contact with that boy and repented to Allah. Now, can I marry her? I never did fornication. She is now very religious. I have doubts whether her towbah was correct or not and whether this marriage will be valid or not.

Q: I am a Muslim but I suffer from homosexual feelings. As per advice from many renowned scholars, I got married. I never disclosed this to my wife before marriage. I still have homosexual feelings. So I kept having these thoughts that I have deceived my wife. So I disclosed it to her and she is ok with it as she loves me a lot and I want to stay with her too. I would like to know if this marriage is valid in the eyes of Allah since I hid this truth from her. 

Q:

1. Is marrying for money halaal?

2. If yes, should the amount given in salami or as a gift be returned after divorce? Is it obligatory in Islam?

Q: When I was in school, I had been in a relationship and for fun my friends wrote a nikaah naama which included all the details like my parents' name, witnesses, lawyer, molvi (my friends pretended to be one of the characters). It even included the mahr. Then a female friend asked us separately if we accept each other as wife and husband thrice and we both said qubool hai 3 times. I had taken it as a joke and ignored it but now after several years, an aalimah I know told me that the nikkah was done at that time and I should either immediately tell my parents about this so that the nikaah would complete or ask the guy for divorce or else I would be doing a major sin. I want to confirm if I did get married or not.

Q: I got married for a second time to a woman who is 32 years younger to me. She married me with all her consent through court marriage 6 years ago and through this marriage Allah blessed us with a beautiful daughter. Recently her behaviour towards me has become very harsh and does not respect me anymore. Alhamdollilah as far as sexual part, it is quite satisfying for both of us.

My question is:

1. Have I committed a sin by marrying a woman 32 years younger than me? I am meeting all her demands successfully. Alhamdollilah by Allah’s blessings physically everything is satisfactory.

2. Can you please let me know how to guide my wife to start respecting me again?

Q: If someone/girl agrees to a "temporary marriage" aka muta marriage to a shia .. does this mean she leaves the fold of Islam? And if so what are the necessary procedures to come back into islam ?

Q: I am planning to get married and proposed for a certain girl. The girl whom I want to marry said that if I accept the condition of not taking a second wife in the future, then she will marry me. Personally, I also do not want to take a second wife in the future. I want to spend my life with my first wife till I die. The question is: can we make the condition of not taking a second wife in the future at the time of the nikaah?

Q:

1. A man says to a woman,’Did You marry Rahim?’ The woman replies,’Yes’ in front of many people. Does it mean they are married?

2. A man says to a woman, ’Are you marrying Rahim?’ The woman replies,’Yes’ in front of many people. Are Rahim and the woman married?

Q: Suppose a man is jokingly saying the ijaab of marriage loudly being all alone in the room. But a woman and two male Muslims from another room hears this and the woman says the qubool in front of these two men. Will they be married?
