Kufr

Q:

1. Does Allah forgive a person who commits shirk and kufr repeatedly? Basically he committed shirk and kufr the first-time, then he realised that he made a mistake so he repented and promised Allah that he wouldn't do it again but unfortunately he broke the promise many times by committing shirk and kufr.

2. What advise would you give to someone to stop falling into shirk and kufr sins?

Q:

1. I read online that if one plays holi (hindu festival) then they are out of the fold of Islam. Is this true?

2. What if one is walking, not intending to play holi, just going out for work or leisure and colour is thrown on them. Are they out of the fold of Islam?

3. I also read that if one prefers holi or thinks it's fun, etc., then it takes one out of the fold of Islam and their nikah will be nullified, is this true?

4. Does just merely thinking this take the person out of Islam and is their nikah nullified?

5. Does just thinking holi is fun or wanting to play it but actually don't play it as they know it is a kuffar thing, are they out of the fold of Islam and is their nikah nullified?

The person would never actually play holi as they know it is against Islam. They just want to know if they just think it's fun, etc. what affect would it have.

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

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.
