Pragya Thakur defeated Congress' Digvijay Singh by about 3 lakh votes in Bhopal.
The two saffron leaders met on Sunday while campaigning for the Lok Sabha polls.
The 2008 Malegaon's mosque bomb blast accused, Sadhvi Pragya is on bail. She joined the BJP on April 7. The party has decided to field her from Bhopal for these general elections.
"A Hindu can never be a terrorist. They have fabricated false cases to frame her. It was a conspiracy for vote bank politics," Amit Shah said, while addressing a rally at Rajnagar in Chhatarpur district, on Tuesday.
Addressing BJP workers in Bhopal, Thakur had claimed that Karkare died during the attacks as she "cursed" him for torturing her.
The polling will take place on May 12.
"We do not regret but are proud of demolishing the Babri Masjid. We removed the waste from our Lord Ram's temple," she said in a TV interview.
The Commission served the notice even after she had withdrawn the remarks and asked why action should not be taken against her for breach of the election code. Thakur has been given 24 hours to respond.
Thakur is out on bail in the 2008 blast case and she is under fire for claiming that IPS officer Hemant Karkare was killed during the 26/11 Mumbai terror attack as she had "cursed" him for "torturing" her.
According to media reports, Thakur said former Mumbai Anti-Terrorist Squad chief Hemant Karkare, who died in action during the Mumbai terror attacks, had falsely implicated her in the Malegaon blast case and hence, died because "of his karma."
The applicant, the father of a blast victim, has questioned Thakur's candidature citing she had got bail on the ground of her poor health, but "she is healthy enough to fight the election."
Thakur is an accused in the 2008 Malegaon blast case in which seven people were killed. She was in jail for nine years and is presently out on bail.
It began with a tweet from the People's Democratic Party (PDP) leader, Mehbooba Mufti, on Wednesday slamming the Bharatiya Janata Party's (BJP) decision to name Malegaon blast accused Sadhvi Pragya Singh Thakur as its Lok Sabha poll candidate from Bhopal.
