Nikaah & Marriage Issues

Pocket money for the wife

Q: I just want to ask a question about the money for a wife. I am pregnant my husband fulfills my all needs, but he does not give me pocket money as I need it for myself. e.g for my parents. My husband can afford it. Should he give me money or not?

Marrying within close family

Q: I read a Hadith which says,” The prophet (peace be upon him) once told one of his companions to choose a wife from a tribe different to his, and then to choose for his son a wife from a third tribe and to seek for his second son a girl from yet another tribe”. My question is, is this Hadith authentic? If so then it means that marriages should not be done within close family as cousins etc. I appreciate if you please comment.

Adultery

Q: I need some information on adultery. What is the sin of visiting whore houses and indulging sex with a prostitute. What happens to the nikahaa whilst indulging in this?

Nikaah after an illicit relationship

Q: Musa and zainab are involved in illicit relationship for couple years, by the occurrence of the days and nights their relation became more solid because now zainab fell pregnant. To get rid from this shame the two families decided to get them married. What will be the hukam of this nikkah according to shaafi and hanafi mazhab and what will be the solution to this matter (for these people to be saved from this shame Islamically)?
