Women's Salaah

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?
