He said the calls came after Zulqarnain said on his Facebook page on Sunday that he would soon expose people who had taken bribes.
"All these people who are saying negative things about me...they should wait for five more days then I will show them my background and status. After five days I will show them their background and place and also those who don't take money and those who have taken money," Haider wrote on his page.
The wicketkeeper left the national team earlier this month and fled Dubai for London where he has applied for asylum, saying he was under threat from people who wanted him to cooperate in fixing matches.
Zulqarnain was a member of the Pakistan squad whose tour of England this year degenerated into chaos when test captain Salman Butt and opening bowlers Mohammad Asif and Mohammad Amir were suspended following spot-fixing allegations.
