How to find first match in multiple files

Is there a way for the find command to search for the first match or occurrence of a string or pattern within each of multiple files? I've been using the usual syntax:

 find dir -iname '*.ext' -exec command 'pattern' {} \;

Keep in mind this is not same as the commonly-asked problem of producing the first result from a search using find with -quit or head -n 1.
