Mr Musharraf had previously vowed to end his self-imposed exile and fly back to Pakistan by the end of this month to revive his political career.
He faces arrest on arrival as he is accused of failing to provide adequate security for former PM Benazir Bhutto ahead of her assassination in 2007.
The former military ruler, who stepped down in 2008, denies wrongdoing.
On Friday Pakistan’s Prime Minister Yousuf Raza Gilani repeated that Mr Musharraf would be arrested if he did return.
Mohammad Saif, general secretary of Mr Musharraf’s All Pakistan Muslim League, told journalists in Dubai: “Gen Musharraf will return to Pakistan, that’s for sure.
“But we are waiting for the tension between the government and the Supreme Court to subside.
He told journalists in Dubai that the government would seek to use Mr Musharraf’s return to divert attention from its failures.
Mr Saif gave no date for Mr Musharraf’s return.
