Mr Akhtar said the cleric, Tanveer Peera Hashim, should be immediately arrested for his "irresponsible and outrageous" comments.
"Secularism doesn't mean ignoring or tolerating minority communalism. This irresponsible and outrageous cleric Tanveer Hashim should immediately be arrested for trying to create communal tension in Bengaluru," Javed Akhtar, 73, tweeted.
The cleric kicked up a controversy with his remarks made in the presence of state minister Shivanand Patil during his sermons on the occasion of Ramzan prayer at Vijayapura in north Karnataka a few days ago.
The remarks sparked a row as cow slaughter is banned in Karnataka.
Tanveer Hashim is the head of Hashim Pir Dargah at Vijayapura, a popular Muslim shrine.
The video of his purported remarks has since gone viral.
The minister chose to remain quiet after the cleric made the controversial remarks.
BJP spokersperson S Prakash urged the coalition JD(S)-Congress government to register a case against the cleric immediately.
Mr Prakash also questioned the "double standards" of the JD(S)-Congress coalition government, asking why it should have different yardsticks for party MLA and former union minister Basavaraj Patil Yatnal and Tanveer Hashim.
"Both JD(S) and Congress call themselves secularists. Why are they silent? When the government can book a case against Basavaraj Patil Yatnal, why not the cleric? Why this double standards? It is certainly questionable," he said.
RSS ideologue Ratan Sharda said he does not expect any action from the Congress when in the past they haven't been able to stop Mani Shankar Aiyar from making controversial remarks.
"When they could not stop Mani Shankar Aiyar from making useless comments, so how can we expect them to take action against the minister (Patil) and the cleric? They will never do it," he said.
The cleric's remarks came days after a purported video of Mr Yatnal asking corporators to work only for Hindus, who voted for him, and not for Muslims, went viral on social media.
