Women's Issues

Q: We know from the hadith that a woman is not allowed to travel at all a distance more than 3 days and 3 nights (78km) without a mahram. But would this prohibition be relaxed in the case where a female has to acquire deeni knowledge? 

Example, in her home town there are absolutely no madrasahs. So a girl travels without a mahram for more than the safar distance and then joins a girls' boarding madrasah and lives there. Will this be permissible under the circumstances? 

If not allowed: what is the status of her acquiring knowledge, will her ibaadaat be accepted there, etc?

Q: Can a widow in iddat meet her niece's husband?

Q:  Do women need to repeat the prayers prayed in between blood? If on Tuesday 3pm she sees some slight red spots, and then clear for the rest of the day, then 5pm the next day then clear, then 9am the next day she sees more blood and her period actually starts, must those prayers be re-prayed?

Q: Isha began around 5:40pm today and I started my period around 7:45pm. I hadn’t prayed Isha yet as sometimes I just want to delay it. 

Do I have to make qada of this prayer when my period ends?

Q: If a divorce is given, does the wife have to leave the husband's house?

Q: If a woman kept a nafl fast and her haidh came during the day, will she have to make qadha of that fast?

Q: Can a woman in haidh write Durood Shareef in the books provided to write, as it has the name of Allah in Arabic and I would end up touching the word Allah which is written in Arabic. 

I have been doing it during my haidh, but I read somewhere that a woman in haidh cannot touch the name of Allah that's written in Arabic
