Interest money

Using interest money to pay tax

Q: As per new Saudi rules, they are charging many levy, taxes, even charges of exit/entry and iqama charges. My father have 7 dependents under him which and we are paying government more than 40,000 riyal from our halal earned money. In this case, is it possible to pay them by depositing our money in fixed deposits and give them interest amount and get rid of it? 

Is modern day interest haraam?

Q: I would like to know if riba falls under the category of western interest? A lot of scholars have said that it does not and it is permissible. I would like to know the reasoning behind this and why it is or is not permissible. I have been reading a lot about this topic and when the word riba is translated it can have a large number of meanings.
