Q: A person touched his wife's sister's daughter (his wife's niece) with lust when she was 15 years old. His wife now wishes to get her son married to her niece. Will it be permissible for her son to marry her niece? The wife does not have knowledge that her husband touched her niece with lust.

Q: Is it permissible for a father in law to hug and kiss his daughter in law as she is young?

Q: I have made up my mind to take a second wife. I have four young children from the first marriage. I am concerned about not being able to spend enough time with the kids to participate in their tarbeeyah as I am a busy doctor and usually come home after Maghrib. Can I keep some or all of my kids with me when I am spending the evening and night with my second wife?

Q: A woman's husband's parents are sleeping in the same room as the woman (their daughter in law) and her husband (their son). It has been almost 3 weeks and the daughter in law is very annoyed as it is an invasion of her privacy and her parent in laws should not be sleeping with her and her husband.

The woman and her husband sleep on the bed whilst her husbands parents sleep on the floor with a mattress. So the woman and husband are higher from the ground than the parents.

The woman (daughter in law) was laying on her side and the husband (son) got up moving the duvet. It was unknown that the father in law was sitting upright on the floor mattress to which he would be able to see the woman and her husband on the bed. Whilst the woman was laying on her side, her right side of her chest, the skin/flesh of her right breast was exposed. Only the skin was exposed and not the full breast. The father in law uinintentionally looked and then quickly lowered his gaze, he shouldnt have been looking in the first place to be honest.

The woman told her husband and he said that his father wouldn't have seen it, he has weak eyesight.

If the father in law had looked at the skin exposed does hurmate apply and affect the nikah of the woman (daughter in law) and her husband (son)? 

Q: Can a man slap his wife?

Q: Does the mother of a woman have to give consent for the daughter's nikaah? Or is the permission of the daughter's father or wali sufficient?

What if a mother disagrees but the daughter and father agree, is the nikaah valid? The mother never said there was an Islamic reason for her disapproval she always gave un-Islamic reasons for her disapproval.

Q: Is it prohibited to have sex during pregnancy?

After child birth, is there a specific time period to avoid sex?

Q: Hanafis can only give wealth as mahr whereas Shaafi'ees can recite a surah, etc. Does this only work if both boy and girl are Shaafi'ee or if one is Shaafi'ee and the other Hanafi?

Q: I have contacted many doctors. I am like a girl, my body, chest, etc. My feelings are also like a woman. I know that this is not allowed in Islam and it is a sin. I am controlling myself but I want sexual relations with an older man and want to marry. My doctor confirmed that I am gay. What should I do?
