In the Harvard Cite Them Right style, you should include a page number for both direct quotes and paraphrasing.
This rule applies to citations in your writing. For example:
Khan (2015, p.3) ...
or
...(Khan, 2015, p.3).
It does not apply to the full reference as this performs a different function: telling your reader what the source is (book, book chapter, article etc) and giving specific details on how to find it (by following the format specified in the Harvard guide).
Please check the University's referencing page for more details on this.
