Q: In ghusl, if I do not not wash my feet and feet's sole and it gets wet by water which I used for ghusl on other parts of the body and with my unwashed wet feet I roam in my house, is my floor or clothes impure and can I pray on my floor and with these clothes? Because I wore my pants when my feet unwashed but wet which transferred wetness to my pants probably impure water. And In fajr I am unable to find enough time to pray with purity because I have urine drops problem in fajr which may take 1 to 1 and half hours to get pure which I don't and cannot give can I be considered mazur for fajr time and can I pray in jamaat in this condition? Please suggest some zikr or Dua or salawat to get rid of waswasas (satanic whisperings) which have taken over my life now I miss two prayers on average daily because of it.

Q: I was getting help from the teacher for a questions and I was sitting and some bad sexual thoughts came to my mind and I randomly was shaking my leg to and the thought gave me a weird feeling in my private area but soon left also I was shaking my leg but not for the purpose to get rid of that feeling as soon as I realized I even was shaking my leg I stopped but since I was concentrating on my work the thought left my mind and later when I got up I felt a slight bit of wetness and when I came home there was a bit of discharge.

Q: Do girls have to perform wudhu or shower after vaginal discharge? This white colored emission has been happening before puberty. My Umm says she's not sure in this case but it is better to perform wudhu.
