Kufr

Q: I am a student at a Christian school. There, we are forced to join church sessions everyday in a church and be part of the prayers. Can I attend these sessions provided I do not believe in Christianity?

Q: My question is that I want to know are Christians for Muslims kaafir? If yes where can I find this subject in the Quran.

Q: I have a question which I hope you can clarify: If someone denies that a certain Sunnah is a Sunnah, under which conditions would this be kufr?

Q: Is there any action which can take a person out of the fold of Islam or it is only wrong beliefs that take a person out of the fold of Islam?

Q: I know someone who has bad thoughts, that he does not want, but they keep coming back and now he is confused about a particular situation. He had bad thoughts and he did not intend to say anything, but he worries because when he exhaled he thinks he heard part of the bad thoughts come from his mouth or like a motion on the tongue or he said part of it under his breath without wanting to say that. So the question is : If somebody has a thought of kufr and they said part of it or all of it without intending to or wanting to and they are angered by it, does this count as kufr?

Q: My wife was frustrated because of something and she said repeatedly that she is no more Muslim. But now she is worried about that and needs to ask about the status of her religion and we are also worried about our nikaah.

Q: If a Muslim woman bears a child of non Muslim man due to adultery will she be a kaafir? She is planning to keep the baby and make him a Muslim and she wants to make tawbah. Will she enter Jannah?

Q: I want to ask about the reasons which cause the loss of a person's Imaan. There is a man who does not fast in the Holy month of Ramadaan. He does not say prayers regularly. But whenever he says the prayer, he only recites "Ashadu Allah Ilaaha Illallah" in attahiyyaat and ends the prayer. He does not recite complete kalima and Durood etc. He gives the reason that he does so because he does not like reciting anyone elses name in Namaaz except ALLAH. He also does not believe in Qurbaani and says it is better to give money to a poor person than spending money on this event. Whenever something is explained to him-in the light of Sunnah/Hadees, he does not agree/believe and says just tell me where this thing is written in the Quran. About Hajj he once said it is just a way to increase the treasures of the Arabs. My question is that can this person be regarded as a Muslim and if he marries a Muslim woman, will the Nikah be vaild?

Q: I do magic tricks and I do cardistry (some sort of art form like juggle and make pattern using cards). My local ustaz said its ok to do magic tricks unless it does not make people worship you or think you have supernatural power. But I also found on some website that say it is haram to play poker and playing cards because it will make you tend to do haram things (maisir in this case). However about magic tricks with cards, it does not do anything that makes me tend to do anthing haraam. I also did not like to play poker because it's only a game of chance. I also perform my prayer. I only do it for fun.

Q: In songs some words are kufur words (example rab will forget) so if you listen or spell that word, what is the hukum in islam?
