While talking to the media outside a court in Islamabad, Mr Sharif said, "What did I say that was wrong in the (Dawn) interview?"
After attending the emergency meeting, Prime Minister Shahid Khaqan Abbasi said the former premier had clarified to him that his statement was "misreported".
The National Security Council (NSC), in a special meeting on Monday called by the military, rejected Sharif's comments on the Mumbai attacks in an interview with Pakistan's Dawn newspaper as "incorrect and misleading", the prime minister's office said in a statement.
Abbasi said there was no tension between the civil and military.
They observed that it was very unfortunate that the opinion arising out of either misconceptions or grievances was being presented in disregard of concrete facts and realities.
The spokesman said the PML-N as the country's premier popular national political party and its supreme leader (Nawaz Sharif) need no certificate from anybody on their commitment and capacity to preserve, protect and promote Pakistan's national security.
Sharif had admitted publicly on Friday that Pakistani terrorists were involved in the 26/11 attacks and questioned why Ajmal Kasab and nine others were allowed to cross the border to carry out the carnage in Mumbai in 2008. The army, along with Sharif's own former interior minister Chaudhry Nisar Khan, blamed it on India accusing it of not cooperating with Pakistan on the 26/11 attacks and running a campaign to vilify Pakistan in front of the world.
"Nawaz Sharif has rejected Monday's statement of the NSC which had condemned his controversial remarks and the entire nation is in a state of chaos since", he added.
A spokesman for Mr Sharif on Sunday said, "At the outset, statement of Nawaz Sharif has been grossly misinterpreted by the Indian media". Explain it to me.
Why can't we complete the trial."I mean raised question on the timing of the revelation, and said Sharif was in power for four years and did not speak out a word about the Mumbai attacks".
Sharif's remarks have sparked a debate in Pakistan with his opponents criticising him for toeing the Indian line while many praised him on social media for having the courage to speak the truth.
