Sharif, who was forced to quit before time for the record third time, addressed a huge rally in downtown Rawalpindi, after starting his journey from Islamabad to Lahore to project his political strength.
It took him more than 12 hours to cover about 30 km distance which takes about half an hour under normal circumstances.
Sharif, 67, said that it was pity that none of the prime ministers in the 70-year history of the country have been allowed to complete their tenure.
He asked the people to make a pledge to guard their mandate so that elected representative are not removed through undemocratic ways.

"Make a promise me that you would get your mandate respected. Promise me you won't allow your prime minister to be humiliated this way," he said.
He warned the supporters that their elected leaders would again be sacked in future if "you do not protect your rights". "It has happened with me for the third time. Is this not an insult to your vote?" he said.
He posed a question the gathering, if they accept the decision. The public responded with big "No", prompting Sharif to say: "One court gave its decision, now this people court is given its decision".
He termed the gathering as verdict by the people court - a referendum.
"This gathering here serves as a referendum. The court of the people of Pakistan has given its verdict in my favour," he said.
"I am going home and I do not want you to get me restored. But I want you to stand with me for the development and betterment of the country," he said.
Later the crowd dispersed peacefully while Sharif went to the Punjab House in Rawalpindi to spend the night.
Sharif will resume his journey to Lahore at around 11.00 am today and the planning is to reach Gujranwala, which is last big city before Lahore, before end of the day.
Last month, a five-member apex bench had found Sharif "unfit to hold office", ruling that he had been "dishonest to the parliament and the courts in not disclosing his employment in the Dubai-based Capital FZE company in his 2013 nomination papers.
