Tahaarat and purity

Q: A few days ago I explained to my family that impurities transfer, but it seems that either they don't understand or they are not taking the matter seriously. I saw my mum touching my nephew's nappy. She didn't care whether her hands were soiled or not. She washes my clothes and irons them as well. Can I perform Salaah. I told my family that urine is impure and they all say yes that it's impure but I think that don't understand that impurities transfer. What should I do. Yesterday I wanted to perform Salaah then I left it because I thought I became impure. If they continue to became lax about impurities, what should I do?

Urine drops problem

Q: I am a mazoor suffering from urine incontinence. I have 3 questions:

1. After making istinjaa and before making wudhu I always drip some urine in between, can I still make wudhu?

2. If a mazoor intentionally urinates one or two drop of urine, is his wudhu still valid?

3. Is reciting Qur'an forgiven for a mazoor?

Haraam relationship with a non-Muslim

Q: I have a non Muslim female friend. I want her to come to Islam and become a Muslim. For this I always make dua for her and show my best character (akhlaaq) to her. But when I talk about religion she tells me she doesn't believe in any religion but she believes in Almighty God that He is One. She is engaged in bad habits such as: cigarettes, wine, boy friend relationships, etc. When I told her to leave these things she got irritated and told me don't interfere in my life. I have my own life. What I want I will do. I don't care whether it is good or bad. Please tell me in this situation what should I do?
