Sharing one's lifestyle photos on Instagram

Q: I want to build a professional Instagram profile for networking, career growth, and attracting business clients. To build this image, my pictures will naturally show my lifestyle, including how I dress and the nice places I visit. I previously avoided this out of fear of Riya (showing off) and Nazar (the evil eye). If my intention is purely professional and not to boast, is it permissible to share these lifestyle photos? How do I draw the line between presenting a good image and showing off?

Reusing a grave of a family member when there is space available in the graveyard

Q: Is it permissible to reuse a grave of a family member, burying the deceased at 4 feet deep, whereas the original deceased was buried at 6 feet deep? The remains of the first deceased (who passed away 3 years ago) would thus not be exposed. 

There is however sufficient space available in the grave yard.

Accepting a gift or working for someone whose income is haraam

Q: 

1. If all of a person's income is haraam, can you accept a gift of dawat from such a person (i.e. you are sure that he has no halaal wealth or income)? 

2. Can you work for such a person? The work you are doing for him is of a halaal nature, but he is going to pay you your salary from haraam money. 

3. If such a wishes to purchase something from you and you are certain that the money he is paying with haraam money, will it be permissible to sell to him? 

4. Will there be any difference in the ruling if the person (whose income is haraam) is a non-Muslim?

Receiving gifts from a person who works in the bank

Q: I would like advice regarding the following: 

My father works in the bank and it's his only source of income. After finding out that interest is war with Allah Ta'ala, I decided to find a job and move out. 

My question is, now that I have a job and moved out, all the stuff that were bought for me by my father what do I do with it? Do I give it away or can I still use it? My clothing, I have tools my father bought and basically everything I have is from my father, what do I do?
