Nikaah & Marriage Issues

Q: I was forced to marry a person whom I did not like. I told my mother many times that I dont want to marry this person but my family was not willing to call off the marriage. One night before the nikah I consumed sleeping pills with intention of commuting suicide (Astagfirulkah). The next day I was under the influence of medicine and I don’t remember anything. During my subconscious state my nikah was done with the boy. I was not in my complete senses. I informed my husband about the suicidal step that I have taken and that I don’t want to live with him. Is this Nikah valid as my consent was not given in complete consciousness.

Q: We are Muslims and a childless couple. We adopted a baby girl and we don't know about her parentage. We want to give her our name and identity and raise her as our own, without telling her that she was adopted. We don't know who are her parents. Is this allowed?

Q: Can a married woman stay the night at her (married) sister's house, without her husband's permission?

Q: In Islam, a husband and wife are rewarded for satisfying eachother in bed, but what if a boy marries a girl by doing sihr (jaadu) on her and makes her agree to marry him? In that case will that person be rewarded by Allah for satisfying her or will it be counted as a life time rape? 

Q: Is it haraam to chat or look for a wife online?

Q: Before I married, no one told me about how mahr works. They told me that I must take whatever he gives or I cannot marry him. Is it right or what?

Q: Is it permissible to marry one's cousin (dad's brother's daughter) who is older then one by four years?

Q: Can we use toys with some kind of sound to stop a baby from crying?

Q: Is it possible to marry an ex-wife's daughter? I know a man that married a woman 13 years older and she never told him she has a daughter almost his age. They are not together any longer and he wants to propose to the daughter. Is this permissible considering he didn't know this? He didn't have intercourse with her since finding out as he was very hurt and shocked.

Q: A girl's father made her nikkah to a guy. She wasn't in the nikkah. She made her father her representative. After nikkah she wasn't living with the guy. She was still living at her father's house. Few months later she came to know that the guy is not good so she decided to break the nikkah. But her father said there was no nikkah done. After that she got married to another guy and now she is living with him. But one of her relatives is saying that her nikkah was held at that time and now she has done nikkah over nikkah. Now theres confusion about her nikkah whether it was done or not. She is now married to another guy. Is she doing zina? Is that nikkah valid? She can't even get divorced from that guy she left because these people have become their enemies.
