The Joint Investigation Team (JIT) chief Wajid Zia had summoned the prime minister to appear before the six-member probe team at 11:00 AM (11:30 IST) on June 15 with all documents relevant to the case.
Amidst tight security, Sharif will appear before the probing officers at Islamabad's Judicial Academy - which is temporarily turned into the JIT's secretariat.
The summons was issued to Sharif, 67, after he returned last Saturday from Kazakhstan where he had attended the Shanghai Cooperation Organisation (SCO) Summit.
Sharif has denied any wrongdoing.

The Joint Investigation Team had questioned Sharif's sons -- Hussain and Hasan -- last month over the family's alleged improper business dealings.
His eldest son Hussain was questioned five times while Hasan, the youngerson, was summoned twice.
The court last year took up the case and issued a split decision over allegations of money laundering when Sharif was prime minister in 1990s.
The JIT is bound to complete the probe in 60 days unless it is granted additional time.
It is for the first time that a sitting prime minister would appear before a high-level probe team traditionally constituted to investigate high-profile criminal cases.
It is not yet clear that Sharif will be questioned for once or would be called again like his two sons.
Media reports had also said that Finance Minister Ishaq Dar may also be questioned tomorrow by the JIT before Sharif's appearance.
