How to give the quote's reference

[Mubtasim]

I found the quote "It so happens that one of the greatest mathematical discoveries of all times was guided by physical intuition." by George Polya in the book "The Mathematical Mechanic" by Mark Levi.
So, if I want to add this quote, whose name should I put on the author section and should I put the book name?

TIA.

Quotes should be listed under their original source. That means that if they are cited in another book, it would not be linked.
