doestn it need 5k coins to setup 1 node??? how can you setup 3 with 3k coins  have i misunderstod something 

staking is like interest rate from banks, and this is prohibited in Islam.

So lets say i just download the wallet, i bought 100block and then what? i just close wallet and that is it or do i have to do something so they are not staking?

I got a question about POS, that is very important for me to be answered, because of my religion. the question is:  Can i choose to hold block but NOT TO STAKE my coins, lets say i got 100Block in my wallet for 2 years, then i still want them to be 100 block i dont want Stake reward is this possible, or is my wallet force-staking automaticly?
