Using zakaat funds to pay for expensive medication

Q: I am a dialysis patient requiring medication every month for approximately 1 year and if not taken, it can be life threatening. Due to the price of these medications being expensive and way out of my budget, so a Muslim medical organisation offered to pay for the medication but through zakaat funds. My question is that despite being sahib-e-nisab, will it be permissible to accept it in this dire circumstance?

Touching one's mother after masturbating

Q: I have a question with regards to hurmut mussaharah. Unfortunately, I was watching porn/masturbating one evening, where suddenly my mother entered the room. Although I did not expose myself in anyway, I was greeted and touched whilst I was still in an excited state from the haram I did. I remember feeling something inappropriate and trying my best to suppress the feeling, although I have no such feelings at all normally (sorry for going into detail, but I remember I still had an erection before they entered and there was a feeling after the touch which was out of my control). I also remember warmth from the touch. Has hurmut mussaharah taken place? Please advise me what to do.

Marital problems

Q: My son married a girl of his choice. She is short tempered and does not take care of his clothes and food. She pushed him twice to give talaaq. He does not want to do anything against Deen. He thinks he is stuck with her for the rest of his life. She demanded to live separately so he got her a house. But they still fight a lot. He is very unhappy. What does the Deen say in this regard? Can he separate her?
