Ghusal

Nikaah performed in the state of janaabat

Q: If a woman or man bathed before their nikah and didn't know they had to rub their scalp but every strand of hair (atleast they thought) was wet would this mean the nikah would be invalid as ghusl was not done completely? What about a woman who bathed after her periods before her nikah and missed some parts of ghusl but thought she was cleans. Is nikah invalid?

What if she did ghusl like this for 4 or 5 months after nikah and did ghusl like this after periods and sex? Does nikah invalidate? What if any part of the ghusl was done incorrectly or missed what is the effect of nikah? Is it invalidated?

Doubting if one gargled during ghusal

Q: Girl has been baaligh for about 5 years. She remembers being particular about doing ghusls from her menstruation but now shes getting doubts that sometimes she might have got yellow discharge in her menstruation days in the first few years and she didnt do ghusl again because she used to get yellow discharge in her paaki days (as white discharge when drying up can turn yellow) but now shes getting doubts and she used to have a bath eveyday (like washing her whole body) but cant remember if every time if she washed her nose and gargled so now how much qadha namaz should she pray coz her ghusl might be done at the wrong time.

Preparing food and eating in the the state of janaabat

Q: I had ejaculation last night and don't have ghusal. I have 3 questions:

1. If I wear clean clothes, do they become impure (naapak) if my body has sweat and my clothes become wet as my body is impure (naapak).

2. If I drink or eat something without ghusl will it be haram?

3. If I prepare food and wash my clothes with water in this condition will both of these things become impure if I dont have ghusal?

Doubting whether wetness is mani or discharge when waking up

Q: I got up and noticed wetness but as I was having this kind of discharge most of the time nowadays and before sleeping there was some discharge, so I didn't do fard ghusl and read fajr and recite Quran. But I was feeling like I was sinning as the amount of discharge was not this much before sleeping and on the other hand it was like normal discharge which I was experiencing normally. Now is my salah valid or not?
