Helping a poor Muslim with zakaat

Q: Can I zakaat give to a person who needs help for his business. He is poor but he can fullfil his daily food and clothing needs. He has a home also in the village but he can not do business due to money, so that his financial condition can improve. If we can help him, Insha Allah his condition will get better. Please guide me.

Premarital relationship

Q: I had been engaged for one year and I just talked to my fiancee on mobile and crossed every limit on mobile. She left me after one year and immediately married  her bhabi's brother . I saw her after her marriage, she came before me on call in front of her family. She said that she told her parents that she did not agree to the engagement but her mother said she is lying and her bhaabi had done black magic on her. I am very confused and upset and can't forget the talks and her.

Facing the wrong direction when performing Salaah

Q: A family moves into an apartment, they use a well known Qibla finding app to locate the Qibla direction and pray. Months later a neighbour points out that the direction is wrong and they must face the other direction. The difference is about 90 degrees apart. What happens to those Salaah that were prayed in the incorrect direction, are they valid or do they need to be repeated? 

Urine drops problem

Q: I am suffering from urine incontinence, but my problem is very strange. Whenever after washing my private part, a drop of urine comes out after washing it, rest of the time urine drops comes but randomly.

1. My question is if I keep washing private part, a single drop of urine will keep coming right afterwards, am I considered a ma'zoor?

2. My second question is what if I got 10 minutes in between (washing private part and till the drop of urine comes out), do I have to read my Salaah at home or musjid?
