Interest money

Q: I wanted to find out about the following to questions regarding interest.

1. Is it permissible to hire out people with interest money to repair potholes which the government supposed to do and are not doing so. Would it affect the maslah if the person who gave the interest money to repair the roads is also using the roads and taking benefit from this interest money?

2.Can a person use interest money to pay off the interest of a bond?

Q: Can I use interest money for victims in Turkey and Syria?

Q:

1. Can I use interest earned on a savings pocket linked to my main account to offset bank charges on the main account?

2. Can I give the interest earned on the savings pocket to a family member who is in an overdraft?

Q: Can I assume that all the secular banks in the country deal in riba if I live in a kafir country or would I be sinful for assuming evil of people without proof?

Q: Is it permissible to open an interest-bearing bank account with the only intention of donating the accrued interest to a non-Muslim cat feeding organisation?

Q: A person deals mostly in cash and does not deposit in the bank in order to avoid showing too much income and paying exorbitant amounts of tax to the government. However, he cannot purchase large items such as properties and cars etc as it has to be done with "legal" money.

The only way out for him will be to take a loan from the bank in order for his purchases to be recognized legally. He will offset the interest payable with the interest he receives from his bank account.

Can this be a valid excuse to enter into an interest bearing loan with the bank?

Q: What is the status of the kuffaar and the money they earn from riba? Is it halaal for them? Can we accept money for goods sold from this? 

Q: Can interest money be given to a domestic worker to be used for building her house with no intention of it being a gift?

Q: Is profit paid on a savings account by the bank halaal or haraam?

Q: I had around $48.5 of interest money in my Australian bank account. I wanted to get rid of it by giving it to a poor person. A few days back, in my office, there was a collection for a bushfire relief fund and it required staff to buy some raffle tickets which the company was giving a gift to the winner. I thought of giving that interest money as a donation so I told them that I am happy to contribute $50 but won’t take any raffle tickets. They requested a lot so I took the raffle ticket but Alhamdulillah I didn’t win any prize.

Now my question is, was my niyat of getting rid of the interest money fulfilled or not? Do I still need to give that $48.5 to a poor person or will the amount of $50 which I gave in charity suffice?
