Kufr

Q: I wanted to perform salaah so I asked my husband to switch off the tv, so he said "Ey" as if he was annoyed. Is such a comment kufar?

Q: I suffer from doubts regarding many things. I am constantly remembering jokes and statements I made in the past that may have been statements of kufr. I have recently read about people singing certain songs that may have taken them out of the fold of Islam. Alhamdulillah I do not listen to music anymore. However I remember listening to and singing the same songs many years ago. I did not know the meaning of these songs at the time. I am now doubting the validity of my nikah and legitimacy of my children due to my actions prior to and after nikah. Is my nikah valid if I have commited these actions prior to nikah?

Q: Do we regard Shiahs in our country as kaafir ?

Q: If someone got a problem and instead of making dua to Allah he tries other ways to come out of it. Is this low iman or kufr. (He is not making dua because he thinks that maybe Allah will not fulfill his duaa.) E.g. A financial problem came to him. He starts asking people for money. He doesn't make dua for the same reason above. Is it kufr or low iman?

Q: If someone commits kufr unknowingly or forgetfully or unintentionally, does he require to say shahadah again? If yes, then how it is that if someone committed kufr unintentionally and still he got out of Islam and became kafir? How can he be guilty of kufr while he had no intention doing it?

Q: My question is if a Muslim watches fictious super hero movies like spiderman and other super hero movies in which they show a super hero getting alive again after death. The superhero that is considered god of thunder, and other fictious movies which show devils, evil spirits (horror) etc. in. Does watching all these superhero movies nullify a person from Islam? I know watching movies is not permissible but I want to know does this nullify Islam? Because lot of children and adult Muslims watch super hero and horror movies of these types and enjoy.

Q: I played very good football. My friend told me "nice Ronaldo". I smiled at him, thinking and accepting that I am Ronaldo and becoming happy about it. Ronaldo is a Christian footballer. Did I commit kufr by thinking and becoming happy that someone called me a Christian (by calling me Ronaldo)?

Q:

1. If someone does kufr (by mocking islam) after that he comes to know its kufr, is it necessary to say shahadah and repent?

Case1: I am asking this because if a person doesn't know its sin, he won't be getting any sin right? Then why is shahadah and repentance required (if he is not gettig sin).

2. If I said to someone that "making fun of islam is kufr and whoever does this is, is a kafir and needs to repent and say shahdah again to become muslim." Instead of knowing the correct ruling, i just purposely told him to do repentance and say shahadah again to become muslim. Did i commit kufr by making halal haram by telling someone to do an act which is not required and telling them only if u do this then you become muslim. 

Q: If a Muslim has a doubt concerning an Islamic thing, like he heard someone say something about Islam but its widely accepted thing and he gets doubt that if its true or not. If true where is the proof? Like these thoughts. Now I he gets free time and wastes it. Will he be regarded as a kaafir?

Q: If a non muslim is made known about islam and he is in doubt about his religeon. If he spends free time on useless things and doesn't search about Islam and dies. Will he be regarded as a kafir?
