The Punjab home department approved their request for parole on Thursday.
They have been released for five days to attend the funeral of Shehbaz's mother Begum Shamim Akhtar.
The PML-N leaders had asked the government to release them on parole for two weeks for the funeral. She passed away in London on November 22.
