Q: There was a time few years ago when, due to OCD, I would remain in a napaak state, na'oodhoobillah. One day my father insisted that I should make Wudhu and perform Salah as Shaytaan was playing with me.I did not want to perform Wudhu because I felt that my feet were napaak and therefore if I washed my feet and wore the slippers that my parents use & then walked in the room in which they perform Salah with wet feet, the carpet in that room would become napaak. I however had no choice but to do so.

Q: I have a question about urine drops. I took my four year old to the toilet and I wiped her first and her urine dropped on my hands as I went to reach out for the water I'm not sure if the urine went anywhere else. It was a very small drop but I didn't think it would go anywhere up until I went to wash my hands.

Q: Whenever I talk to a girl, even if it's a normal conversation, some liquid comes out from my private part in a very very minor amount. What should I do? If this happens I will be talking a bath 24/7 and how could I handle my practical life before marriage? Even if I am talking on the phone I feel seduced without any reason, having just a normal conversation. Please help me, I offer 5 times Salaah and remain in wudhu. I do not watch TV a lot, no movies, songs. One in a day if possible. My life is ruined because of this. Help me.

Q:

(A) I had a shower at night. I washed my slippers and feet whilst in the shower.

(B) Then I went out of the house for just over 2 hours wearing the same slippers. When I returned home it is most likely that, by that time, my slippers were dry.

(C) I then got in to the sleeping bag, which I have borrowed from my parents home and which I am using at my house. At the time I went to sleep in the sleeping bag it is most likely that my feet were dry. At the time of sleeping, I thought to myself, when I wake up in the morning I must wash my feet and slippers again as a precautionary measure.

Q: Will clothes with najaast become pure if washed in the washing machine?

Q: There were very small tiny spots of madhi on my undergarments (very much smaller than the excusable diameter) and when I make istinja the front organ is wet and touched the area but nothing got onto me so as the impurity was of excusable amount can I regard myself as pure even after the wetness from my body touched that area?
