Husband not allowing children to visit their non-Muslim grand-mother

Q: I am a revert alhumdulilah. I am in a dilemma regarding visiting my mother who is Hindu. My husband does not allow my kids to visit her because she has a temple in her yard. It's not like the kids play outside. My family has a lot of respect that I am a Muslim and they have never forced us into doing anything unlawful or haram. My mother is now heartbroken as she can't be with her grandchildren and I feel bad visiting her without the kids. Her tears are haunting me. I know that a mother holds Jannat under her feet and to make a mother cry is the biggest sin. I can't take this anymore I'm miserable and how do I earn Jannat one day in sha Allah if my mother is hurt. So please advise as I can't hear or see my mother cry anymore.

Father committing zina with niece

Q: My father is in a relationship with his brothers daughter (which is haraam). We came to know this two years back...when we confronted him...he left us...he is not ready to leave her...he is committing zina. Last two years he is not in contact with anyone from the family...in these circumstances what is to be done? Is the nikaah still valid between my mother and father? When he left he said that he will send papers to my mother...but till today there is no single word from my father... He is not accepting halal relationship?

Reciting duas and Quraan in a bathroom without a toilet

Q: A person has a bathroom with a sink, shower, etc. The toilet is enclosed in a shower door type enclosure. So the rest of the bathroom is not considered the toilet. Would it be correct to recite duas etc. there when making wudhu? Will it be fine to take a Quran inside the bathroom, recite Quran there whilst watching children in the bath? Not in the toilet, but in the rest of the bathroom.
