The opposition party also reminded Congress of bringing Hitler's ideology to India first by imposing Emergency and said the people of the country who have not forgotten it will give a "befitting" reply to it in the polls.
BJP said it will continue to reply to Congress' use of such language by not crossing its limits and accused Gandhi of being "rattled" due to the "impending" defeat.
"Rahul Gandhi has attacked the Sangh and BJP's leader, whom he fears, by addressing him as 'Hitler'. It is unfortunate...BJP does not accept the use of such language for its leader. BJP considers this a statement given by Rahul Gandhi after being rattled by the impending defeat in polls.
"Congress always has a slip of tongue ahead of every election. In the past, Congress leaders had used phrases like 'Maut ke saudagar' (merchant of death) and the people of Gujarat have given a befitting reply to it in the assembly elections. This time too, the people of the country will give a befitting reply to it," BJP spokesperson Shahnawaz Hussain said.
He accused the Congress of using such language and phrases ahead of every election and said the ruling party and its leaders are losing patience due to their poll debacle ahead.
Hussain said Rahul Gandhi has forgotten that while he is giving sermons to his party's spokespersons, he himself is not adopting restraint and, instead of listing the achievements of his government in the last ten years, is resorting to use of such language.
Hussain charged since Congress is devoid of any issues ahead of polls and is unable to take on Narendra Modi, they are resorting to the use of abusive language.
"While victory and defeats keep happening in politics, the use of abusive language in the fear of defeat does not bode well for the country's polity," he said.
Accusing Arvind Kejriwal of serving as a "B-team" of Rahul Gandhi, he said the AAP leader had visited Gujarat ahead of Gandhi's visit there, who will now follow him in Maharashtra, where Kejriwal is addressing rallies.
"In 10 years, Rahul Gandhi has not given a reply on his government's rule at the Centre...there has been no word on corruption, price rise or unemployment.
"On the kind of words like 'Hitler' and 'maut ka saudagar' used by Congress in Gujarat, Congress has come down to use of abusive language. The 121 crore people of the country will give a befitting reply," he said.
The BJP leader said it does not want to cross its limits, even though it can give a reply to the Congress in the same language and with the same tone and tenor.
