If you haven't read the original source, cite the secondary source in your reference list and provide credit to both the original source and the secondary source in the body of your text. For example, (Primary Source Author, date, as cited by Secondary Source Author, date).
For more detailed examples, see APA Style's "Recommendations for Secondary Sources" and the Purdue OWL example for "Citing Indirect Sources".
