A five-member Supreme Court bench last month disqualified Mr Sharif for dishonesty and ruled that corruption cases be filed against him and his children over the Panama Papers scandal, forcing the prime minister to quit for the record third time.
Addressing a huge gathering in Gujarat on the third day of his journey from Islamabad to Lahore via the Grand Trunk (GT) Road to display his political might, Mr Sharif said even the judges who disqualified him failed to point out a single example of corruption against him.
"I cannot accept this joke. Can you accept this joke that you elect someone, then he is disgraced and ousted," he said.
"May I ask why I was ousted? Did I commit any kind of corruption? I am innocent and did not commit any financial wrong. That has been said by the judges who disqualified me.
Then why I have been ousted," the 67-year-old veteran politician said.
He said that the people's vote has been trampled upon as millions of people elected a leader and a couple of people or five judges disgraced and sent him home.
Mr Sharif, who could not complete his term for a third time, also asked the gathering, "Should I sit back and accept the verdict or fight the injustice?"
The people responded in unison with a big 'No', prompting Mr Sharif to ask them to stand by him.
"If you do not want me to sit back then you would have to stand by me. Then stand by me to change the fate of this nation. Promise me that you would do what I tell you," he said.
Mr Sharif said the time had come to change the country.
"We would have to make sure that your vote is respected.
He also announced that he would announce his future plan of action and asked his supporters to wait for it.
Mr Sharif stepped down after being disqualified by the Supreme Court on July 28 and after staying in Murree and Islamabad, embarked on road journey to his home in Lahore in the company of thousands of his supporters.
He was greeted by supporters lining up on the both sides of road as he came out of the Punjab House in Islamabad on Wednesday, making it impossible for his motorcade to move. He covered about 30 km in 12 hours to reach Rawalpindi where he addressed a big rally.
Yesterday, he resumed his travel from Rawalpindi and reached Jhelum in the evening and addressed an even bigger rally there.
Later, he rested at a scenic hotel on the banks of the River Jhelum.
He left Jhelum at around 12 PM and stopped in Gujarat for Friday prayers and addressed his supporters.
He has left for Gujranwala and will cross small towns of Wairabad, Gakhar Mandi etc. He is expected to halt briefly at some places to address his supporters.
According to the scheduled of Pakistan Muslim League Nawaz (PML-N), Mr Sharif is expected to spend the night in Gujranwala. He would leave for Lahore in the morning and is expected to reach there at 4 pm tomorrow.
