Clothing and Covering the Aurah

Q: If a woman performs salah with 3/4 length trousers and then tights under them, wherein no part of her leg is visible, is her salah valid?

Q: During salaah, I sometimes wear a shirt which has a low collar, so a bit of my upper chest (under the bone below the neck) neck gets visible. Is the salaah valid?

Also, how much portion of the chest should be covered by men during salaah? 

Q: I have difficulty concerning covering my awrah during prayer as a female.

1. I have quite a small forehead, and the hairs that cover the sides of my forehead are not the same length as my hair overall, but they’re longer than a person’s usual baby hairs. It causes me to overly look in the mirror and fix my scarf before salah just incase any show, and also causes me to bring my scarf down really close to my eyes. Due to this difficulty, if these certain hairs show during salah, can I overlook this?

2. Another thing I have a lot of difficulty covering are my wrists. Even If I try to use long sleeves, sometimes during sajdah the sleeve of my wrist gets lifted upwards (like towards the ceiling) - if that makes sense - due to me laying my forearms on the ground. Today, I saw my sleeve on my wrist during salah and it looked lifted and I had a slightly strong feeling that the way it looked it was probably showing my awrah but I didn’t attempt to change it because I was confused about what to do. I couldn’t tell if more than a quarter was showing or not from the angle I was sitting. I was also not sure if I should have moved to fix it regardless of if it was less than a quarter.

- If I notice that less than a quarter of awrah is showing during salah, then do I fix it or can I leave it?

- Can you confirm if I properly determined the quarter of my arm during salah because I’m not sure if i’m doing it right. To determine if a quarter of my arm shows, does it mean that my elbow is considered the halfway point? I feel guilty because I felt like if I had a strong feeling that my awrah was showing, I should have hidden it.

Q: Do I have to wear a topi when performing salaah, or can I perform salaah without a topi? 

Q:

1. When I make wudhu, water splashes on my thighs and my pants becomes wet. So when I pray, while in the sitting position, the skin from my thighs become somewhat visible because I wear white pants. Is my prayer valid?

2. When I pray, the wind from the fan hits my clothes and the shape of my private part is visible. Also, when some people go into sajdah while wearing pants, the shape of their testes are seen, is the prayer valid?

Q: I have seen many women read salaah with tights or skinny jeans and they put a burqa over. The burqa ends around their knees and the rest of their legs are visible. Is the salaah valid?

Q: Is it permissible to pray salat wearing a t-shirt which contain a picture of human which is kept coverd?

Q: Is prayer acceptable whilst wearing eyelash extensions?

Q: Is it permissible that a person can offer Salah in a t-shirt that is half sleeved and does not have any image printed upon it? Also what is the ruling regarding three quarter shorts.

Q: Kindly explain the satr of a female in detail... does the forehead have to be completely covered and where does the chin end? Some women insist that the burqa must cover the tip of the chin downwards or else salaah is not accepted. Please clarify.
