Kufr

Fear of committing kufr

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. 

Finding something that looks like a cross on one's phone

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)?

Attending Hindu festivals

Q: In India there are many festivals of false gods. Everywhere people celebrate it. In the IT Company that I work in people also celebrate these festivals. The company makes one entertainment program in which they say to the employees to come the next day with constumes. Then they worship false gods and dance in that program.

Many Muslim people, mostly girls, get involved in that. They wear clothes like the non Muslims. I tell them not to get involved in that, they tell "we are just going to have fun. We are not going to worship any false gods." Are they doing shirk?

Using computer software codes that have Greek names

Q: I'm a computer scientist and in my learning and use, there are often libraries of codes which are very popular and heavily used. They often contain a lot of math or pre built software. The problem is that the library sometimes might have a haram name like jupyter, greek mythology names much like the names of several planets. What should a Muslim to do in this situation?
