Thank you. message-fetch-field works if the point is in a message
buffer. I was not aware of this option. But when the point is in a
gnus-summary buffer, then

        (message-fetch-field "Subject")

returns nil. Even with something like:

        (defun husain--test-message-subject-yank ()
          (interactive)
          (save-excursion
            (let ((subj (message-fetch-field "Subject")))
              (if subj
                  (message subj)
                (gnus-summary-show-article)
                (gnus-summary-select-article-buffer)
                (message (message-fetch-field "Subject"))))))

this still doesn't work as intended because it does not restore the
window if the point is in a gnus-summary buffer pointing to an article
not open.

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