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?

Performing salaah with an empty space in the saff in front

Q: If one prays in congregation, but due to people praying ahead, he cannot join the saffs ahead, is it permissible:

1. To pray behind an empty space between him and the safs ahead where more than two safs can be formed?

2. OR should he pass in front of musalles to go ahead? What about in the Haram Shareef in Makkah Mukarramah and Masjid Nabwi? Are we allowed to pass in front of musalles?

3. If one prayed behind with an empty space ahead, does the salah need to be repeated?

4. If needs to be repeated, if the prayed salah was janazah, what intention to make for the repeated salah, nafl as janazah salah perhaps cannot be repeated?

Father in-law moving daughter in-laws furniture

Q: My query is that my inlaws rented out my portion of the house in my home country. My father in law also sent my furniture and my things to his daughters (my sis in law) room. He did this all without my consent. As far as I think, this is *Amanat* to use others property without permission. Me and my husband are having constant arguments on this as he can do nothing about this. My relation with my husband is getting affected. Please guide how should I handle this sutuation?

Touching one's mother while masturbating

Q: When my friend was 14 or 15 year old, he intentionally touched his mother while masturbating but he is in doubt whether the lust was due to masturbation or due to touching his mother. He has repented from his previous lifestyle. Has hurmat musahara occurred or not?

If it has occured according to hanafis couldnt he take fatwa of other scholars on this because if his father divorces his mother their family will get destroyed as he has other siblings also and they will almost become mad.
