You do not stall because you delay flap extension, you could stall by flying an inappropriate speed for the flaps you actually have and thereby exceeding critical angle of attack while disregarding all preceding warnings (buffet, airspeed low warning, stall warning, stick shaker...). You can safely land without using flaps, provided the runway is long enough to allow for the increasing landing distance. If you stall the aircraft it means you ****** it up big time.
