Women's Salaah

Women facing their toes towards the qiblah during sajdah?

Q: In salah I mistakely thought women were supposed to point both toes towards the qibla in sajdah because I felt like I remembered reading an instruction which said that. My feet were both on the ground horizontally, however the toes were towards the qibla. I’d like to believe my past prayers were ok? Are prayers ok even if women follow the man’s way?

Women reading Taraweeh in jamaat

Q:

1. I wanted to know if two women are reading Taraweeh together, must the one leading for those rakaats stand a little forward and the one following a little behind, or must they stand in line?

2. If one woman isn't reading, can she sit with a Qur'aan next to the one who's reading Taraweeh, and correct her if she makes a mistake ? (The one reading will be reciting in a slightly audible tone, is this permissible as well?)

Performing salaah wearing short sleeves

Q: Firstly I have clothes with short sleeves. All my clothes are these which have almost 3 quarter sleeves. I have almost less than a quarter of my arm uncovered for Namaz. I recently read somewhere that this makes my Namaz maybe invalid. What to do? I have no other clothes with full sleeves other than one or two. I can’t wear them daily.

I go to an academy having male teachers. I cover my head but a little area of my forearm is not covered. So what to do. Do I have to cover the area between my wrists and my forearm or is it fine?
