Some times, womens wear short sleeves due to hot weather in home, but when time comes for prayer use some kind of chadar (shawl) to cover head and arms, is that okey… or sleeves has to be long enough.
The use of the chadar to cover the hands in the entire Salaat will suffice. If the chadar moves out and the hands are uncovered, then it will be Makrooh.
and Allah Ta’ala Knows Best
