Harvard style referencing academic question

Hello,

I would like to ask: How do you use in-text citation, with the Harvard Hull (author-date) referencing style, when you want to quote the specific words of the author, without, however, stating the name of the author in the text?
Is is correct to follow this template (Author, date : page) for example, (Schon, 1994:150) or is there another way to do this?

Thanks, I really appreciate any help you can provide.
