burqa

Q: I have heard that after the haidh is completed, a person may no longer sleep on the same bedsheets, even though the sheets are not messed. The sheets must be changed before making ghusl or if ghusl is taken and the sheets have not been changed, one may not sleep on the bed unless the sheet is removed. Also further this was applied to any scarves or burkas that one may have worn during the haidh for even a short period. Is this correct?

Q: My wife made 2 mistakes in umrah. We are worried that we have to give sadaqa, damm or any other fine for that mistake or it can be ignored.

1. Although we left our home with the niyyat of umra, but when the meekat came she didn't make proper niyat by words. She make proper niyat by words when we reached Makkah.

2. During tawaf she covered her face with full burka as she was worried about her hair becoming exposed.

Q: I read in your book that women's clothes during salaah can't reveal her body shape. My salaah dress is not tight, however when I go to ruku you can see the shape of the knees, going to sajda – shape of back, in jalsah – shape of knees again as I sit, etc. so the dress is not tight but not very flowing and loose. Is it a problem? I have also question about sleeves of the dress. It is not tight, but not that its very wide, when bending an arm it shows shapes of elbow, etc. is it a problem? In one my abaya a sleeve has a tight ending, around 20 cm from a wrist upwards towards elbow. Is this tight ending a problem from making salah in this abaya? Also, is it ok to make salah in hijab (scarf) or only in khimar is ok, because hijab when wrapped around head looks tight and khimar flows down. At home I make it in khimar (till belly), but outside in hijab (scarf), what is the status of common hijab (scarf) for salah? By the way, even khimar falling down the bosom still shows its shape. Is it ok or we have to wear khimar 3 times bigger our size to have many gathers to hide all possible shapes? Is it what we have to try to achieve in our dress for salah and our khimar? In your book its stated that arms of a woman must be under burqa. I checked burqa in the internet and saw a dress that clothes all face including eyes. Is this the requirement, because it is also written in the book that face can be open? My khimar is till belly and its inconvenient to put hands under it for takbeer. Is it ok to do it on top?
