    Husain>           (interactive)
    Husain>           (save-excursion

    Husain>               (if subj
    Husain>                   (message subj)
    Husain>                 (gnus-summary-show-article)
    Husain>                 (gnus-summary-select-article-buffer)
    Husain>                 (message (message-fetch-field "Subject"))))))

    Husain> Is there a gnus function that can build the message in a temp buffer?

In a temp buffer, no, but you can access the article buffer using eg
`gnus-with-article' or `gnus-with-article-buffer', or even
`gnus-with-article-headers' if you only care about the headers.
