"I understand the frustrations of a bowler in the heat of the moment but as an international sportsman one needs to control these emotions whatever may be the situation and always respect the opponent.
"Stuart, by pleading guilty, realised his mistake and I'm sure he will not repeat the same again."
England looked on course to wrap up an innings victory before tea when Pakistan lost their sixth wicket soon after lunch, but Haider's partnerships with Mohammad Amir and Saeed Ajmal gave them a surprise lead of 112 going into day four.
After his throw at Haider, Broad quickly held up his hand in a gesture of apology, but the Pakistan camp did not feel he had done enough.
Pakistan skipper Salman Butt stated: "Cricket is a gentleman's game but I think England got frustrated. The throw was just one thing. There were plenty of words as well, that everyone could see, and people kicking the bowling marks.
"It's just frustration when you have been bowling too long. It's not good to see people throwing balls intentionally at others and not even apologising properly."
England's Graeme Swann, who saw the gloss knocked off his Test-best 6-60 by Haider's runs and Broad's indiscipline, insisted there was "no malice" in the actions of his Nottinghamshire team-mate.
Swann said: "Broady apologised straight away. It was just a sign of the frustrations that were going on."
If Broad transgresses in such a way again, he could be slapped with a one-Test ban.
