"I was indeed pained to read Kapil Dev's highly provocative comment on Yuvi's party life. As a mother, I am hurt mainly because Kapil has known Yuvi ever since he was born," an upset Shabnam said in a statement.
"He has obviously gone by the media reporting which was proved wrong," she added, referring to the late-night party that Yuvraj allegedly attended during the Asia Cup.
Kapil on Sunday had criticised Yuvraj for putting parties over cricket and had urged him to concentrate on his game to realise his potential.
Shabnam said Kapil had a past of his own and should therefore refrain from taking a high moral ground.
"All I want to remind Kapil that people who stay in glass house shouldn't throw stones at others," she fumed.
"He should introspect his misdeeds during the time he played cricket. If he rewinds his life, he will find that he wasn't an angel," she said.
According to Shabnam, Kapil's comments are stunning, considering her son has won applause from several former greats for his game.
"Sad that such a great cricketer should stoop so low when across the border Hanif Mohd has been comparing Yuvi with Sir Sobers," she said.
