Party general secretary Bhupender Yadav also attacked Congress over its opposition to the government's legislative agenda, saying while for Modi democracy was "form of and by people", for Congress people meant a family.
In a press conference, Yadav parried questions over whether the policies of Reserve Bank of India under its Governor Raghuram Rajan also contributed to the growth, saying Modi was leading the team and everybody was its members.
BJP has officially maintained that it had nothing to say about the issue.
Yadav said the economy has shown all-round growth, including in manufacturing and agriculture, adding 25 per cent growth in unorganised sector meant that numbers of jobs were also increasing.
The Rajya Sabha MP credited the Centre's commitment, responsibility, fiscal discipline and management under Modi and also praised Finance Minister Arun Jaitley's "economic skills".
"The growth has come despite poor monsoons, political adversities and sluggish economy... Modi has led the country to become the fastest growing economy in the world," he said.
Economy grew by 7.9 per cent in March quarter to consolidate India's position as the fastest growing major economy with a five-year high growth rate of 7.6 per cent for the full fiscal on robust manufacturing growth.

"The Centre has opened new opportunities in the
manufacturing sector. It has built a new structure of social security for its people," Yadav said.
"The GST bill is opposed only for petty political benefits. Similarly, Aadhar and CAMPA laws are being opposed which is a direct attack on the spirit of federalism of our Constitution and country," he said.
But even in these political adverse situations, the government has kept its promise of 'Sabka Sath - Sabka Vikas', he said.

Reacting to another issue, Yadav referred to a "factually incorrect" story published in a Gujarati daily and shared with the media the regret published by it.
"It was a factually incorrect story. They have published their regret yesterday," he said.
