Former England player Bob Willis had earlier made comments suggesting that Ajmal illegally bends his elbow during his bowling action.
Ajmal has defended his action on a number of occasions and chose to concentrate on his performance when quizzed on the comments.
The spinner said: "I am just concentrating on my bowling and it is basically up to the umpires and referees to say if there is a problem with my action.
"Does it trouble me that someone in England questions my action? It's no problem."
Ajmal had earlier recorded career-best figures of seven for 55.
