Keeping the name Hajirah

Q: My daughter's name is Hajirah but we are confused as to what is the actual spelling of the name. Please let us know the correct spelling as in English and urdu. Also the meaning of the name.

Asking for khula if husband wants to take a second wife

Q: We know that in Islam a woman is forbidden from asking for khula for no legitimate reason. We also know that she cannot prevent her husband from marrying a second wife.

In the case where the wife deeply knows that she cannot cope with having a co-wife and this causes her alot of emotional harm, hatred towards her husband which causes her to not wanting to fulfil his rights nor stay with him or look at him, in this case, is that a legitamate reason for her to ask for a divorce if the husband tells her that he is going to get married to a second wife?

1. Can I use the Govt. computer and internet for further learning advanced technologies?

2. Can I use it for listening to Islamic lectures?

Protection from black magic

Q: My mother suffered with asraat a few years back. Alhumdullilah she got cured back then with the help of Quran. That time the raqi did say that there was black magic done on my mother but he didn't say who did it. I have observed my phupo (dad's sisters) that she only visits our place on full moon days like purnam or something like that...

I don't know what it is but it makes me worried for my parents. We, as a family have seen hell this long. I don't want to think anything evil about my phupo but it just flashes in my mind... Please help me with any dua or anything that could make me get rid of this feeling.
