Q: My question is about nikah in paradise. If we like someone and did not get married due to his/her death but still like him/her from the bottom of our heart and want to marry him/her and pray to Allah to meet in jannat, is it permissible to pray like this and will Allah give us the right to choose him/her as a spouse in jannat?

Q: I have a very embarrassing question but I can't handle it anymore. The thing is that I am in my twenties, I don't masturbate or speak to any guys but I toss and turn at night. Unable to sleep because of my insane sexual desires that are now eating me alive. I will never masturbate but I can't handle this. It's too frustrating. I want to scream in pain and I just know that the advice everybody will give is try to get married but it's not in my control at all. If Allah Ta'ala isn't willing for me to be married right now, if He hasn't sent anybody my way for me to be married to then how can I?

Q: I'm in urgent need of something. Is there any kind of amal or dua so that Allah grants my wish/hazaat?

Q: Due to physical illness I (psychiatry disorder) lost my physical desire. I am 20 years old and no one knows in our house that I lost my physical desire. So what order of parda is implemented on me for my non muhram. Should I observe parda from them now as I observed parda from them in the past?
