The incident came following the Pakistan accountability court's sentencing of Sharif, his daughter Maryam Nawaz and son-in-law Captain Mohammad Safdar Awan (retd) in the Sharif family's purchase of the upscale property.
Former Prime Minister Nawaz Sharif will arrive to Allama Iqbal International Airport Lahore from Heathrow Airport London on July 13, 2018.
Sharif and his daughter, Maryam Safdar, are now in London, where the three-time former PM's wife is undergoing cancer treatment.
She said a consultation was under way over the decision and that their lawyers are looking at the matter from all legal angles.
"Workers from all across the country will reach the airport to welcome their leader", Mushahidullah Khan, a senator with Sharif's Pakistan Muslim League-Nawaz party, said.
Safdar, meanwhile, surrendered himself on July 8 to police in the garrison city of Rawalpindi, where he was arrested after leading a rally of supporters.

Former Punjab chief minister Shehbaz Sharif said on Sunday his party was being bombarded with false allegations.
"Since the road option may be hard for the authorities concerned with regard to provide security cover, a helicopter should be provided to the NAB to avoid problems in the arrest and shifting them (Nawaz and Maryam) to Adiala jail in Rawalpindi after producing them before the accountability court", the official said.
She said the nation was behind her father as they planned to return, whereas others chose to fly out of the country with excuses like "backache", in an obvious reference to Pervez Musharraf.
