Kufr

Renewing one's Imaan due to having a wrong belief

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?

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.
