The court last week had ordered Maryam, Hassan and Hussain to respond the charges by opposition that they bought assets abroad with illegal money.
The five-member bench headed by Chief Justice Anwar Zaheer Jamali took up five identical petition by Imran Khan and other on November 1, demanding probe into the assets of those mentioned in the Panama Leaks.

All three children denied allegations leveled against them.
The court asked about the money trail which was invested in the foreign businesses of Sharif's family and gave seven days period to furnish relevant documents.
It also directed all parties to submit documentary evidence about their claims and charges or denials.
The case is being billed as make or break for the Prime Minister as Imran Khan and others have alleged that foreign assets of three children managed by offshore companies were purchased through corruption and money laundering.
The court initially refused to hear the case but took up the proceeding after Imran Khan announced to lockdown capital Islamabad on November 2.
The court has indicated that it would set up one-man probe commission to thoroughly probe the charges. But it needed detailed Terms of Reference (ToR).
Now the court has asked the parties to submit their ToRs and announced to go ahead with its own ToRs for the probe if difference continue.
It is believed that a negative judgment in the case would seal Sharif's fate.
