Pakistan's former prime minister Nawaz Sharif is set to arrive in Islamabad on Saturday after a four-year self-imposed exile in the United Kingdom, months ahead of general elections.
Sharif, 70, has been in London since November last year after the Lahore High Court granted him permission to go abroad for four weeks for treatment.
According to jail officials, Nawaz, Maryam and Safdar will be released on Wednesday if the order is received prior to the expiration of lock-up time.
Pakistan is bracing for another day of violence that broke out in many cities after the arrest of former prime minister Imran Khan for alleged corruption with the leaders of his party announcing a countrywide strike on Wednesday to protest against the fascist government.
The court also refused to suspend the conviction in the case until the appeals were decided.
The court delivered the verdict after postponing it for four times in the Avenfield corruption case -- pertaining to the ownership of four flats in the posh Avenfield House in London.
Shehbaz, the 70-year-old younger brother of former three-time prime minister Nawaz Sharif, has served as chief minister of the country's most populous and politically crucial Punjab province thrice.

Maryam and her husband are likely to file an appeal challenging the verdict in the Avenfield Properties corruption case.
Pakistan Muslim League-Nawaz (PML-N) president Sharif, 70, and Pakistan Tehreek-i-Insaf (PTI) vice-chairman and former foreign minister Shah Mahmood Qureshi on Sunday filed their nomination papers for the post.
'The army has been open about its determination to keep the PML-Nawaz out of power at all costs.' 'Both the military and the higher judiciary have indicated a preference for Imran Khan's Pakistan Tehrik e Insaaf,' says Rana Banerji, who headed the Pakistan Desk at the Research and Analysis Wing, India's external intelligence agency.
Three cases -- Avenfield properties case, Flagship Investment case and Al-Azizia steel mills case -- were launched by the National Accountability Bureau on September 8, 2017 following a judgment by the apex court that disqualified Sharif.
Sharif, 67, is in London with his wife Kalsum who is undergoing cancer treatment, and has not returned to Pakistan for the court hearing since he was indicted in the graft allegations.
The National Accountability Bureau officials took Sharif, 68, and Maryam, 44, into custody in the Avenfield case, shortly after their arrival at Lahore airport from London via Abu Dhabi. They were flown to Islamabad on a special aircraft and then were taken to the Adiala Jail in separate armoured personnel carriers escorted by police convoys.
The government and people of Pakistan extend their 'heartfelt condolences' to Vajpayee's family and to the government and people of India, the spokesman said.
Authorities arrange helicopters to shift Sharif to jail; 300 PML-N workers arrested.
The two were convicted on July 6 in the Avenfield properties case linked to the Sharif family's ownership of four luxury flats in London.
Meanwhile, Maryam has rejected an offer for better facilities in jail.
Sharif is in London with his ailing wife Kulsoom, who is suffering from throat cancer and has undergone three surgeries so far.
