“May the Merciful One perform for us miracles just like He did for our fathers, in those days, in this time.” (Harachaman in Birchas Hamazon if forget Al Hanisim).

Many question why we could say this Harachaman and pray for a miracle considering miracles generally deplete a person’s merits.  However, the Yeshuos Yaakov explains that when a miracle has publicity and creates a kiddush Hashem, like the nes of Chanukah, not only is it permitted, but it is a mitzvah to ask for such a miracle!
