Kufr

Q: A man made nikaah with a lady. After a few years of marriage, the lady said to the husband that from the age of nine she believed that Allah will accept the worship of the Hindus as they claim to worship God through their idols, though she did not express her belief in words. At the time of their nikaah, she maintained this belief. A few days ago she realised that such a belief is incorrect and has since repented to Allah. What is the status of their nikaah?

Q: If a person got a doubt while in prayer about Hoors. The doubt was something like "Hoors are created from the Noor of Allah". He thought that he had read it somewhere when he actually had not. He said that he will research it after prayer. If he believes it but upon searching he found that it is not true, had he committed kufr? 

Q: Is saying wallah I worship something other than Allah shirk?

Q: Does laughing at wierd funny beard styles constitutes kufr? E.g. Beards just from the side cheeks, a straight line, etc.

Q: I am getting married and I am worried about Imaan and kufr. Since I heard that nikah will be nullified if one of the two did kufr, what precautions should one take?

Is it kufr to like kuffaar daily life ways? E.g. If someone wears kuffar clothes like pants and shirt, if we praise that person by saying that they are looking pretty in this dress, so is this kufr? There are many kuffaar thing which people have adopted nowadays and my husband to be is a duniyadar. Please guide.

Q: Recently I bought a new phone that is designed to be waterproof and it is designed to be such that if it falls from a table it doesn’t break or crack the screen.

A problem, however, is that the designer of the phone placed two steel platters over the phone’s back (I think it is intended to protect the battery and the back of the phone). I know picture making is haraam so I did not take a photo for you to inspect. The two steel platters cross each other and it looks like a cross (two steel platters crossed together, with the upper part of the vertical platter shorter, which is similar to a cross). I personally don’t think the company intended to make a cross shape to appeal people rather the designer probably just thought that this design is either safe or “cool” (it is a Chinese phone company and they are likely not Christians).

Should I return the phone or keep it? Returning it makes me feel a bit guilty as there is no product defect. But keeping it also makes me worried. If I keep how do I destroy the shape (it is made for safety so I don’t know how to remove the platter)?
