Treating the daughter in-law with kindness

Q: A cousin of mines would like to know about the following circumstances. She stays with her in-laws. Cooks twice a week for the family and helps out when she can. Once a week she visits her parents for a few hours. This is according to her husband's wishes and also keeps her parents happy. However her in-law's especially her mother in-law does not like this. She complains to my cousin of shirking her responsibility but she will never say anything in front of my cousin's husband. Is this true? What exactly is her responsibility to her husband and her parents? Or to his? What will Allah Ta'ala hold her accountable for?

Polygamy

Q:

1. Can a husband kiss his wife on lips, hand, cheek and forehead in front of his other wives?

Can all the 4 wives stay together in one house in 4 different rooms each?

Can the 4 wives offer nafl salaah behind her husband in jamaat? They're interested in praying long rakaats, that's why.

Should a person not consider adopting polygamy because it is frowned upon by his countrymen, relatives and parents?

Is a person allowed to marry more than one wife and upto 4 because he wants to have more children (wants children so that he can honor sahaba by giving them their names and make them great ulema of deoband maslak so that they can bring inqilaab in our society) and has more desire for intercourse while his wife is impure, and lastly so that he can change the life of his 4 wives with his piety and make them a strong adherent of sunnat e rasool (Sallallahu Alayhi Wasallam)?

What if parents and wife don't agree for polygamy even after stating sharee reasons? What should one do? Keep quite and listen to them or make them agree to this with hikmat?

Ruqyah

Q: I have been too much worried about the marriage issue of my daughter for three years. Many proposals came for her but nobody return who came to my house to see my daughter. An aalim told me that listening to 'ruqyah' is a treatment of some kind of seher, jinnat and evil eye. So I started to listen, but after two days I saw in my dream that me and my husband were going toward my car which was parked somewhere, as I got closer to my car I felt somebody inside already. As I opened the door of car it was not like car from inside, it was like empty house and a girl was moving here and there madly like she was finding the way out but unable to find the way. When I got up it was 4:00 am and I was very scared. I want to know whether this dream has any connection with listening to ruqyah?

Eating snakes and killing chicken with one's teeth

Q: I have come across a video that is taken from a TV show in Pakistan showing pakistani army members eating snakes and killing chicken with their teeth and drinking its blood and not saying Allah's name while killing. They do all this while safe in their bases where they have all the halaal food available and the means to slaughter the animals is also available. But they are doing this as an exercise for survival if they are lost in a jungle or behind enemy lines. I want to have an Islamic point of view regarding this practice. Is it halaal or haram. Many Muslims who join the army are made to eat many haram animals during their training. Is this all justified by the "necessity" of training the troops?
