Nikaah & Marriage Issues

Q: If a person commits zina with a woman and later on do nikah with her daughter, what must he do now?

Q: May I ask why Muslims have become interested in things like 'sex toys' in marriage? It seems all very strange and weird. What is the cause of this odd interest by Muslims?

I researched this and the manufacture or sale of 'sex toys' was actually prohibited in South Africa by the apartheid government. The ruling was lifted only in 2007 by parliament.

Q: Is it compulsory to have sex on wedding night with your wife to make walima halaal the next day?

Q: Does Hurmat-e-Musaaharah take place if a grandfather touches his grand daughter with lust?

Q: If a woman see's a boy's penis which is not erected and the woman has lust and the boy does not have lust. Can the boy marry her daughter?

Q: My husband cant satisfy me in sex. He did many things to satisfy me but failed. Can I do self sex with my hand and insert anything in my vagina to satisfy myself without telling my husband? If I don't do that maybe I will get involved with someone else. 

Q: I am aware that when a woman is on her periods the area from her belly button to her knees must be covered. But if a woman on her periods is wearing only underwear and the man is wearing only underwear and they both rub their private parts on each other, does this break their nikah as the woman was not covered only her private part was?

Q: I was telling my husband how I read online by a sheikh/imam that it is not allowed for a grown man to be cuddling his mother whilst laying next to her or for a mother to cuddle her grown son like this. He got annoyed and said she's my mother and I don't want to listen to your nonsense. I asked him further and said what are you calling nonsense? He said that you are saying me or my mother aren't allowed to cuddle each other. I said it isn't nonsense it's not allowed. I have told him this probably atleast 2 or 3 times but I don't think he believes me. He has alot of knowledge of Islam alhamdulliah but he has not read the whole of the quran.

1. Because my husband believes that sleeping next to your mother and cuddling her or her cuddling her grown son is not wrong, does this make him an unbeliever?

2. Does this break my nikah?

Q: According to Islam, a Muslim girl cannot marry a Hindu because the Hindu man, being the head of the family would ask the girl to convert. But if the Hindu family does not ask for conversion, then is it alright for a Muslim girl to marry Hindu boy? What is the punishment of a haraam relationship?
