What are the best books about Islamic finance ? And ethical investment?


As a non finance academic professional, what should be the books I should be reading to understand more about Islamic and ethical investment?

Preferably a book which clearly explains why I should consider doing business in ethical and why not traditional banks?

I had a discussion recently with another person whose valid points are

  • banks need some sort of service charges to do their banking operations
  • what if the person who got the loan run away ?

Don’t need to especially answer the question he asked but I would love to read deeper about this
