Congress leader Kapil Sibal also defended Rahul Gandhi's accusation that Prime Minister Narendra Modi was "trading in the blood of soldiers", saying the party Vice President knew what he was saying and people of the country understand the sentiment behind his words.
Hitting out at Shah, who earlier in the day said Congress was playing along Pakistan on the issue, Sibal asked, "Now will leaders who have spent time in jails and are murder- accused tell us that our foundations are faulty and are questioning Rahul Gandhi's lineage?"
"We did not know that BJP will stoop so low that its President will speak like this by terming as faulty those who got freedom for the country," he said, adding that those accused in various cases are giving lectures and this government has no experience in making even statements.
"I would want that the Prime Minister should tell his party chief that such statements are not good in a democracy. But how will Modiji say this as he is himself helpless and is benefitting from this," he said.
"Let the Army do its job, why is the government playing politics over the Army," he said hitting out at Shah.
Coming out in defence of the Congress Vice President for his "dalali" remarks against Modi, Sibal said, "Rahul Gandhi knew what he said. His thought process was clear. You should understand the feeling of Rahul Gandhi when he made the statement, which the people of the country do."
Asked why there was a contradiction in the stands taken by the party by earlier supporting Modi for the Army's act and later criticising him, he said, "When the first statement was made, it was to stand with the forces of this country, just as Sonia Gandhi stood with Atal Bihari Vajpayee."
"BJP should apologise to the nation for demeaning the Armed Forces," he said.
The Congress leader also recalled a 2013 order of the Election Commission cautioning various political parties to exercise caution while making references to the armed forces in their political campaigns so as not to politicise them.
Congress also showed and released a video "Desh bhakti or vote bhakti", showing how Modi and BJP politicised the sacrifices of country's brave soldiers.
the strikes to the people of the country clearly showed how the party was out to derive political benefits out of the army action.
Citing instances in the past when forces had crossed the Line of Control to defend the country, he asked, "Who crossed the LoC in 1965, 1971 and 1999? Did Modi, Parrikar or Amit Shah cross the LoC? Does Indian history start from 2014?"
He also accused BJP of exploiting the action politically unlike in the Kargil war that Congress didn't and said BJP should apologise to the nation for undermining the Army's valour after Shah claimed that the Army crossed LoC for the first time by carrying out surgical strikes on September 29.
Sibal compared Pakistan to a patient who had cancer, and referred the terrorists as cancer cells that need to be killed and Army should carry out chemotherapy as it wants the neighbouring country to be healthy.
He also chided at BJP for touting the strikes, saying that one surgical strike that India undertook will not kill the cancer. "Will the cancer stop and is terrorism over," he asked.
Sibal also raised the issue of reduction in disability pension of soldiers during the current dispensation as the same was same for civilian employees and those of defence forces before the Pay Commission.
He also said that EC had told all parties that in a democracy one cannot make the defence forces a political tool.
Congress chief spokesperson Randeep Surjewala trained his guns on the Defence Minister saying Parrikar has time to exploit the success of the forces to attend "samman samaroh" from Goa to Agra but does not have time to visit the families of soldiers who sacrificed their lives while defending the country.
