Q: There's a thing that is bothering me so much. A friend of mine hates marriage. Once there was a chart in my college that listed the sunnahs of Ambiya, one of them was nikah. She didn't believe that it was a sunnah, we told her that it was. Afterwards she jokingly said that she will cut this off the chart. Is this kufr? If this is indeed kufr and takes her out of the fold of Islam, she is going to be super offended and likely to throw a tantrum because nowadays people don't even know things that are kufr. How do I explain this to her?

Q: If someone says that his marriage is useless in joking way and he doesn't believe it. He knows the importance of marriage but he said the above given words in front of his wife just to crack a joke, so has he uttered words of kufr?

Q: We respect the four imams and we follow the teachings of Muhammad (sallallahu alaihi wasallam) and Quran. There are very mild differences in Namaz as said by the 4 imams with their proofs in hadith. Now I pray without rafadayn and my hands are not on my chest while standing. So does it mean that I'm praying the wrong way, because I see in Saudi Arabia they do rafadayn and have hands on chest. Please help me and make my salah better.

Q: I am looking for the definition of a Sunnah. Is it correct to say that a Sunnah is anything that Nabi صلى الله تعالى عليه و سلم تسليما said, did or liked?

Q: My mother said to me to take a bath and she said that Muslims keep themselves clean, but as I didn't want to take bath and I, in anger said that I am a kafir (God forbid). So by saying in anger that I am a kafir, did I disbelieve?

Q: When performing a sunnah act, does one have to intend to do that act solely because it is sunnah. For example, if one decided to eat less, to follow the sunnah but also hoping to loose weight, is this wrong?

Q: I have a question about magic and attempting to use it or even having another black magician do certain magic on myself. I know this is a form of shirk and engaging in magic takes a person outside the fold of Islam. Does this mean I am no longer a Muslim and is it something that can be forgiven? What do I need to do? 

Q: Does saying words like 'I knew this would happen' or 'they knew she would say that' considered kufr? What about if the one who says this says it just as a prediction, and does not intend to mean that they have knowledge of the unseen?
