be no question that (something will happen/is the case)
To be absolutely certain that something will happen, be done, or be the case. (Note: Often confused with "be no question of" doing something, which means that there is no possibility that something will be done or is the case.) If you ask me, there's no question that there is something fishy going on with the company's cash flow. I just know that if you keep working hard, there will be no question that you'll be promoted soon.
