Modi's remarks at the BJP Parliamentary Party meeting came on the last day of the Winter Session, which has been a washout due to impasse over demonetisation.
Targeting Congress, the Prime Minister alleged that it has always put its interest over that of the country while for BJP the nation's interests are supreme.
He again pitched for digital economy as he appealed to the masses to adopt it as a "way of life" to rid the society of corruption and black money.
He also cited late Left stalwart Harkishan Singh Surjeet to support his government's action.
"Earlier the ruling side, especially Congress, would commit scams like 2G, coal-gate, Bofors and the Opposition would then unite and fight against it on the principle of honesty.
"But now the ruling side, the BJP-led NDA, has started a campaign again black money and corruption and opposition parties are standing against it," he said.
"The Wanchoo committee had said it will boost economy. Now after 45 years we have done demonetisation but Congress is opposing it. The Left has also joined hands with Congress," he said.
Painting Congress as a "votary of corruption", he said it had made a law against benami assets in 1988 but never notified it or framed rules and regulations, ensuring that the legislation never came into force.
On a day that marks the anniversary of Bangladesh's liberation, Modi also targeted the opposition over its remarks on the army's surgical strikes.
The Opposition in 1971-72 did not seek evidence of the army's valour unlike that of today, he said.
