Zulqarnain, having criticised the inclusion of the wicket-keeper-batsman Kamran Akmal in the national team for the upcoming series against Australia and the T20 World Cup in Sri Lanka next month, posted a message on a social networking site.
"The fact is that Kamran has not yet been cleared by the ICC of wrong doing and has only been cleared by the national selectors and Pakistan Cricket Board (PCB)," Haider claimed.
"If he has any clearance letter from the ICC he should show it publicly and if he doesn't do that then I will be forced to come out with the truth," he added.
Haider who replaced the injured Kamran Akmal during Pakistan's controversial tour of England in 2010 said he would make some revelations that involved many Pakistan players if Kamran Akmal doesn't show the clearance letter.
In order to make Pakistan a corruption free country, Haider stated that he was forced to post such a message on his facebook account.
"I have said what is in my mind and until now I have kept quiet in the hope that the Pakistan board will not allow players with question marks surrounding their performances to play again."
He further added saying that the chief selector Iqbal Qasim headed the same department for which Kamran played.
"That is why he has recalled Kamran and this should be investigated," Haider added.
Interestingly, Pakistan's tainted trio - Salman Butt, Mohammad Asif and Mohammad Aamer all the three played for National Bank (the one Kamran played for) in the domestic circuit.
"It had told him to refrain from making statements while pardoning him last year and some disciplinary action could be taken against him," the source said.
While PCB chairman Zaka Ashraf claimed that he had picked Kamran after seeking advice from the ICC on his clearance. But ICC also made it clear that it had issued no clearance and it was purely PCB's decision to pick him.
Though odds are against him, Kamran was quite confident about making his return memorable as he said he would focus on performing well for the country.
"I have been selected in the Pakistan team and my focus right now is on just performing for my country," said Akmal.
Kamran's name was also mentioned during the trails, in London last year.
The cricketer who is currently playing the Sri Lanka Premier League, has been sidelined from the national team since the World Cup in 2011, following his alleged involvement in spot-fixing.
